You say you want cutting-edge hacking tools without having to mortgage the
wife'n'kids? You say arrogant workstation vendors are getting you down? You
say you crave fast UNIX on cheap hardware, but you don't know how to go about
getting it? Well, pull up a chair and take the load off yer feet, bunky,
because...
This is v5.0 of the PC-clone UNIX Software Buyer's Guide posting
current to July 5th 1992.

What's new in this issue:
* Straight from inside Dell, info on the new Dell 2.2
* Technical info on the new 4.0.4 releases from Dell, Esix, and Microport.
* Known bugs in Dell UNIX.
* Numerous minor corrections and additions.
Gentle Reader: if you end up buying something based on information from this
Guide, please do yourself and the net a favor; make a point of telling the
vendor "Eric's FAQ sent me" or some equivalent. The idea isn't to hype me
personally, I've already got all the notoriety I need from doing things like
_The_New_Hacker's_Dictionary_ --- but if we can show vendors that the Guide
influences a lot of purchasing decisions, I can be a more powerful advocate for
the net's interests, and for you.
0. CONTENTS
I. INTRODUCTION. What this posting is. How to help improve it. Summary of
the 386/486 UNIX market, including 6 SVr4 vendors and 2 BSD ports. What's new
in this issue.
II. GENERAL CONSIDERATIONS. A brief discussion of general hardware
requirements and compatibility considerations in the base SVR4 code from UNIX
Systems Laboratories (referred to below as the USL code). None of this
automatically applies to SCO or the two BSD-like versions, which break out the
corresponding information into their separate vendor reports.
III. FEATURE COMPARISON. A feature table which gives basic price & feature
info and summarizes differences between the versions.
IV. VENDOR REPORTS. Detailed descriptions of the different versions and
vendors, including information collected from the net on bugs, supported
and unsupported hardware and the like.
V. HARDWARE COMPATIBILITY TABLES. A set of tables summarizes vendor claims
and user reports on hardware compatibility.
VI. FREE ADVICE TO VENDORS. Your humble editor's soapbox. An open letter
to the UNIX vendors designed to get them all hustling to improve their products
and services as fast as possible.
VII. ACKNOWLEDGEMENTS AND ENVOI. Credit where credit is due. Some praises
and pans. What comes next....
Note: versions 1.0 through 4.0 of this posting had a different archive name
(386-buyers-faq) and included the following now separate FAQs as sections.
pc-unix/hardware -- (formerly HOT TIPS FOR HARDWARE BUYERS) Useful general
tips for anybody buying clone hardware for a UNIX system. Overview of the
market. Technical points. When, where, and how to buy.
usl-bugs -- (formerly KNOWN BUGS IN THE USL CODE). A discussion of bugs
known or believed to be generic to the USL code, with indications as to which
porting houses have fixed them. None of this applies to the two BSD-based
versions.
I. INTRODUCTION
The purpose of this posting is to pool public knowledge and USENET feedback
about all leading-edge versions of UNIX for commodity 386 and 486 hardware. It
also includes extensive information on how to buy cheap clone hardware to
support your UNIX.
This document is maintained and periodically updated as a service to the net by
Eric S. Raymond <eric@snark.thyrsus.com>, who began it for the very best
self-interested reason that he was in the market and didn't believe in plonking
down several grand without doing his homework first (no, I don't get paid for
this, though I have had a bunch of free software and hardware dumped on me as a
result of it!). Corrections, updates, and all pertinent information are
welcomed at that address.
This posting is periodically broadcast to the USENET group comp.unix.sysv386
and to a list of vendor addresses. If you are a vendor representative, please
check the feature chart and vendor report to make sure the information on your
company is current and correct. If it is not, please email me a correction
ASAP. If you are a knowledgeable user of any of these products, please send me
a precis of your experiences for the improvement of the feedback sections.
At time of writing, here are the products in this category:
Consensys UNIX Version 1.3 abbreviated as "Cons" below
Dell UNIX Issue 2.2 abbreviated as "Dell" below
ESIX System V Release 4.0.4 abbreviated as "Esix" below
Micro Station Technology SVr4 UNIX abbreviated as "MST" below
Microport System V Release 4.0 version 4 abbreviated as "uPort" below
UHC Version 3.6 abbreviated as "UHC" below
SCO Open DeskTop 1.1 abbreviated as "ODT" below
BSD/386 (0.3 beta) abbreviated as "BSDI" below
Mach386 abbreviated as "Mach" below
Note: Dell 2.2 is scheduled for release in July. It includes several
significant improvements over 2.1, which it replaces. All information in
the Dell column of the tables and vendor report now pertains to 2.2, based
on information received from Jeremy Chatfield at Dell.
The first six of these are ports of USL's System V Release 4. Until last year
there was a seventh, by Interactive Systems Corporation. That product was
canned after half of ISC was bought by SunSoft, evidently to clear the decks
for Solaris 2.0 (a SunOS port for the 386 to be released late in 1992). The
only Interactive UNIX one can buy at present is an SVr3.2 port which I consider
uninteresting because it's no longer cutting-edge; I have ignored it.
Earlier issues ignored SCO because (a) 3.2 isn't leading-edge any more and (b)
their `Version 4' is a 3.2 sailing under false colors. Can you say deceptive
advertising? Can you say bait-and-switch? Can you say total marketroid-puke?
However, the clamor from netters wanting it included was deafening. The day
SCO landed an unsolicited free copy of ODT on my doorstep I gave in. I don't
expect to actually use it, but I summarize the relevant facts along with
everything else below. Note that ODT is their full system with networking and
X windows; what they call SCO UNIX is missing most of those trimmings.
BSD/386 is *not* based on USL code, but on the CSRG NET2 distribution tape.
Complete sources are included with every system shipped! Mach386 is basically
BSD tools with the monolithic Mach 2.5 kernel and does entail a USL license;
it's based on the Tahoe BSD distribution. For a few extra bucks, you can
get Mach 3.0 (a true microkernel) with *source*!.
LynxOS is a 386 UNIX specialized for real-time work, available from Lynx
Real-Time Systems Inc. of Los Gatos, California. It includes TCP/IP, NFS, X,
etc. Most of the development tools are GNU. The kernel is pre-emptable and
supports threads and dynamically-loased device drivers.
Siemens AG plans to offer a SVr4 port optimized for real-time work in
June 1992. This product will be called SORIX.
AT&T's own 386 UNIX offering is not covered here because it is available and
supported for AT&T hardware only.
All the vendors listed offer a 30-day money-back guarantee, but they'll be
sticky about it except where there's an insuperable hardware compatibility
problem or you trip over a serious bug. One (UHC) charges a 25% restocking fee
on returns. BSDI offers a 60-day guarantee and says: "If a customer is
dissatisfied with the product, BSDI unconditionally refunds the purchase
price." Dell says "30 day money-back guarantee, no questions asked".
There are some freeware alternative UNIXes available for the 386/486. None of
these are yet complete and mature hacking environments, but they show promise
(and require much less in minimum hardware to run). They are:
386BSD:
Under development by Bill & Lynne Jolitz & friends (this is the same 386BSD
project described in Dr. Dobbs' Journal some time back). This OS is based on
the NET/2 tape from Berkeley and strongly resembles the commercial BSD/386
release described below, and like it is distributed with full source. The aim
is to produce a full POSIX-compliant freeware BSD UNIX. At the moment it comes
up single-user in root, and utilities as basic as grep are still missing.
However, the whole kernel and TCP/IP is working (which means the hard part is
done) and development is proceeding rapidly. There's a lot of traffic in
comp.unix.bsd about this project.
Linux:
This is a POSIX-emulating UNIX lookalike, being written from scratch and
currently in beta. At the moment, it's less complete than 386BSD because it
doesn't leverage as much pre-existing code, but the kernel and development
tools are up and usable. No TCP/IP yet, but they have local sockets for X.
Linux is changing so fast that more description would probably be more
misleading than enlightening. There's an active linux group on USENET,
comp.os.linux, and a (now less active) linux-activists mailing list; to
subscribe, mail to "linux-activists-requests@niksula.hut.fi". Up-to-the minute
info is also available by fingering torvalds@kruuna.helsinki.fi.
Hurd:
This is the long-awaited and semi-mythical GNU kernel. It's being worked on
by the Free Software Foundation (the people who brought you emacs, gcc, gdb and
the rest of the GNU tool suite) but it's not ready for prime time yet. It's
said to be a set of processes layered over a Mach 3.0 kernel. The 386BSD and
Linux developments both lean heavily on GNU tools.
There is one other not-quite-freeware (cheapware?) product that deserves a
mention:
Minix:
This is a roughly V7-compatible UNIX clone for Intel boxes, sold
with source by Prentice-Hall for $169 (there's an associated book for
a few bucks more). It's really designed to run in 16-bit mode on 8086
and 286 machines, though the UK's MINIX center offers a 32-bit kernel.
UUCP and netnews clones are available as freeware but not supplied
with the base system. A large international community is involved in
improving Minix; see comp.os.minix on USENET for details.
These freeware and "cheapware" products exert valuable pressure on the
commercial vendors. Someday, they may even force AT&T to unlock source to stay
competitive...
Finally, there is a class of commercial UNIX clones that claim to emulate UNIX
or improve on it without being derived from AT&T source. The leading products
of this kind for 80x86 machines seem to be Coherent and QNX. The following
information about these has been supplied by various USENETters:
COHERENT is a small-kernel UNIX-compatible multi-user, multi-tasking
development O/S for $99.95 that uses less than 14Mb of disk space, runs on most
286-386-486 CPU systems, has a 64k limit C compiler and over 230 UNIX commands
including text processing, program development, administrative and maintenance
functions. It resides on a partition separate from DOS and can access the DOS
file system with the DOS command. It has no network or Xwindows support, but
cnews and rn have been ported and it has its own newsgroup, comp.os.coherent.
It is fully documented with both a comprehensive 1200 page manual and an
on-line manual. Mark Williams Company provides excellent support including a
UUCP access BBS and has just announced Release 4.0, the 386 version of
COHERENT.
II. GENERAL CONSIDERATIONS
To run any of this systems, you need at least the following: 4 MB of RAM and
80MB of hard disk (SCO says 8MB minimum for ODT 2.0). However, this is an
absolute minimum; you'll want at least 8 MB of RAM for reasonable performance.
And depending on options installed, the OS will eat from 40 to 120 meg of the
disk, so you'll want at least 200 meg for real work. To run X you'll need a
VGA monitor and card, and 12-16MB RAM would be a good idea.
Installation from these systems requires that you boot from a hi-density
floppy (either 3.5" or 5.25"). Most vendors offer the bulk of the system on a
QIC 1/4-inch tape; otherwise you may be stuck with loading over 60 diskettes!
In general, if the initial boot gets far enough to display a request for
the first disk or tape load, you're in good shape.
USL SVr4 conforms to the following software standards: ANSI X3.159-1989 C,
POSIX 1003.1, SVID 3rd edition, FIPS 151-1, XPG3, and System V ABI. 4.0.4
ports conform to the iBCS-2 binary standard. The SVr4 C compiler (C Issue 5)
includes some non-ANSI extensions (however, note that as of mid-1992, no SVr4
ports other than AT&T's have been formally POSIX-certified). SCO meets all
these except System V ABI and SVID 3rd edition; however, it does conform to
SVID 2nd edition.
All SVr4 versions include support for BSD-style file systems with 255-character
segment names and fragment allocation. In general this is a Good Thing, but
some SVr3.2 and XENIX binaries can be confused by the different size of
the inode index. You need to run these on an AT&T-style file system. SCO
UNIX 3.2v4 (thus, ODT 2.0 but not 1.1) has an `EAFS' file system which adds
symlinks and long filenames. Old SCO binaries can be confused by long
filenames.
All SVr4 versions include the UNIX manual pages on-line. Dell stocks
Prentice-Hall's SVr4 books and will sell them to you with your system (in lieu
of printed manuals) at extra cost. You can order them direct from
Prentice-Hall at (201)-767-5937. Warning: they ain't cheap! Buying the whole
13 volumes will cost you a couple hundred bucks. Esix, Microport and UHC
have their own manual sets derived from the same AT&T source tapes as the
Prentice-Hall set; Esix charges extra for them, but Microport and UHC both
include them with their systems.
SVr4 includes hooks for a DOS bridge that allows you to run DOS applications
under UNIX (the two products that actually do this are DOS Merge and VP/ix).
Most vendors do not include either of these with the base system, however.
All these systems support up to 1024x768 by 256 color super-VGA under X. The
640x480 by 16 colors of standard VGA is no problem; everybody supports that
compatibly. However, X servers older than the Roell or X11R5 version (that is,
MIT X11R4 or anything previous) are hard to configure for the clock timings of
your controller and monitor scan frequency unless you have one of the standard
combinations USL supports or your vendor has configured for it.
There are a couple of known hardware compatibility problems the USL code
doesn't yet address. See the KNOWN BUGS section near the end of this document.
III. FEATURE COMPARISON
To interpret the table below, bear in mind the following things:
All these products except BSDI/386, Mach386 and SCO ODT are based on the
SVr4 kernel from UNIX Systems Laboratories (USL), an AT&T spinoff. Thus they
share over 90% of their code and features. Product differentiation is done
primarily through support policy, bug-fix quality and add-on software.
The `USL support?' column refers to the fact that USL support is a separate
charge from the source license. With the former, a porting house gets access
to AT&T's own OS support people and their bug fix database, and the porting
house's bug fixes can get folded back into the USL code.
These systems come either in a "crippled" version that supports at most two
simultaneous users, or an unlimited version. Generally the vendors do allow
you to upgrade your license via a patch disk if your requirements, but this
invariably costs slightly more than the base price difference between 2-user
and unlimited systems.
The "run-time" system in the price tables below is a minimum installation,
just enough to run binaries. The "complete" system includes every software
option offered by the vendor; it does *not* bundle in the cost of the
Prentice-Hall docs offered by some vendors as an option. You may well get
away with less, especially if you're willing to do your own X installation.
The `Upgrade plan' section refers only to upgrades from previous versions
of the same vendor's software.
The numbers under support-with-purchase are days counted from date
of shipment. The intent is to help you get initially up and running.
The engineer counts below are as supplied by vendors; .5 of an engineer
means someone is officially working half-time. The `Uses USENET' column is
`yes' if there is allegedly at least one person in the engineering department
who reads USENET technical groups regularly and is authorized to respond to
USENET postings reporting problems.
A dash `-' means the given feature or configuration is not offered. A `yes'
means it is currently offered; `soon' means the vendor has represented that it
will be offered in the near future. A `no' means it's not offered, but there's
some related information in the attached footnote.

(p) At present, you must buy Mach386 Autosupport to get SLIP.
(q) The SCO networking bundle includes PPP, as will ODT 2.0.
(r) Mark Boucher <marc@cam.org> has written a PPP driver for ESIX
The SCO information is included by popular demand for comparison purposes.
In the price figures, the `runtime' system is SCO UNIX 3.24; the `complete'
system is ODT with development tools.
In general, the SVr4 market breaks into two tiers. The bottom tier is
Consensys and MST; low-ball outfits selling stock USL with minimal support for
real cheap. The top tier is Dell, Esix, Microport and UHC; these guys are
selling support and significant enhancements and charge varying premiums for
it. Your first, most basic buying decision has to be which tier best serves
your needs.
One further note: it *is* possible to buy these systems at less than the list
the vendor charges! I found some really substantial discounts in one
mail-order catalog ("The Programmer's Shop"; call 1-(800)-426-8006 to get on
their mailing list, but be prepared to wade through a lot of DOS cruft).
IV. VENDOR REPORTS
Vendor reports start here. Each one is led by a form feed.

support@sco.com --- support requests (support contract customers only)
SOFTWARE OPTIONS:
SCO's package and option structure is (excessively) complicated. At the
moment the `bundles' to keep track of are:
SCO UNIX System V/386 Release 3.2 Version 4.0
SCO UNIX networking bundle, consisting of:
SCO UNIX System V/386 Release 3.2 Version 4.0
SCO TCP/IP 1.2.0
SCO NFS 1.2.0
SCO Open Desktop 1.1, consisting of:
SCO UNIX System V/386 Release 3.2 Version 2.0
SCO TCP/IP 1.1.3
SCO NFS 1.1.1
LAN Manager Client, PC-NFS daemon, PC-Interface server
X (currently X11R4 server/clients, Motif 1.1.2, X.desktop 2.0)
Ingres
DOS Merge (2.0)
SCO Open Desktop 2.0, starts shipping early July, consisting of:
SCO UNIX System V/386 Release 3.2 Version 4.0
SCO TCP/IP 1.2.0
SCO NFS 1.2.0
LAN Manager Client, PC-NFS daemon, PC-Interface server
X (X11R4 server/clients, Motif 1.1.4, X.desktop 3.0)
DOS Merge (2.2?)
Note that Ingres (the database) is being *removed* from the ODT bundle.
There is a special Ingres price for ODT customers, and Ingres has committed
to offering a 50% discount till the end of '92.
ADD-ONS:
There are piles of them. I was most impressed by the docs for the CodeView
debugger and MASM assembler, but the presence of ISAM support, SQL support, and
what looks like a commercially-viable database tool would probably be more
significant to the ordinary commercial user.
SCO bundles with X also include 18 clients (what in marketingese are called
``personal productivity and groupware accessories and controls'') which
include: mail, help, edit, paint, term, print, login, clock, color, session,
mouse, lock, and admin (official names all prepended with "SCO") as well as
DOS, load, and calculator clients.
SUPPORT:
You get 30 days of free phone support with purchase.
ODT support is $895 per year.
SCO has BBS coverage and a local support operation in the UK and Germany.
FUTURE PLANS:
ODT 2.0 will include X.desktop 3.0.
HARDWARE COMPATIBILITY:
See the appendix for details. SCO provides a Hardware Compatibility
Guide with its software.
COMMENTS:
The docs are impressive; you could get a hernia trying to lift them all.
TECHNICAL NOTES:
There's an `MPX' kernel available from SCO that supports multiprocessing.
Though this is a 3.2 kernel, SCO has added support for SVr4-like symbolic
links and long filenames to Version 4.
SCO has a standard driver announcement protocol which allows the
utility hwconfig(C) to print out detailed hardware configuration info by
inspecting a file generated at boot time. Note: this report doesn't catch
what's actually *attached* (unlike, say, Dell's showcfg), just what's
configured.
SCO's cross-development and DOS emulation support is unusually rich. It
includes lots of system utilities for I/O with a DOS filesystem, as well as
cross-development libraries and tools in the Development System. Microsoft
Windows 3.0 and Windows 3.0 applications are supported (in real mode), and
future releases will support Windows 3.1 and associated applications.
Graphical MS-DOS applications are supported in CGA graphics mode within an X
window, and VGA graphics are supported in full-screen mode.
WHAT THE USERS SAY:
XENIX is the UNIX port hackers love to hate, but at 70% of the market SCO
must be doing something right. In general, SCO UNIX and XENIX are reputed to
be a very polished and stable systems. Unfortunately, they also drive
developers crazy because of numerous tiny and undocumented divergences between
the SCO way and the USL-based releases.
REVIEWER'S IMPRESSIONS:
The SCO support system is heavily bureaucratized and prone to thrash when
processing questions of unusual depth or scope. While probably adequate for
the random business luser, hackers are likely to find the contortions
required to get to a master-level developer very frustrating.
SCO in general has the fairly serious case of corporatitis you'd predict
from their relatively large size --- no-comment policies and
compartmentalization out the wazoo.
On the other hand, they sent me an unsolicited free copy, and I got huge
amounts of useful technical and hardware-compatibility info "unofficially" from
SCOer Bela Lubkin <belal@sco.com>. Gee. Maybe I should flame vendors more
often... :-)
NAME:
Consensys UNIX Version 1.3
VENDOR:
Consensys
1301 Pat Booker Road
Universal City, TX 78148
(800)-387-8951
{dmentor,dciem}!askov!root
SOFTWARE OPTIONS:
None. With the whole system selling for $495 why bother?
ADD-ONS:
Basically this is a stock USL system with the stock USL bugs, except the
installation sequence has been improved considerably. Good tools for
configuration management and system administration on a network of Consensys
machines are included.
SUPPORT:
You get free phone support until your system is installed, to a maximum of
90 days. After that they charge per half-hour of phone time. They like to
do support by fax and callback.
They have 1 (one) support tech. Ask for Reuben.
They have a support BBS at (416)-752-2084.
Knowledgeable customers report they're good about supporting the bits they
wrote (see below) but terrible at dealing with generic SVr4 problems.
FUTURE PLANS:
They haven't settled on an upgrade policy yet.
There are plans for a disk array product.
HARDWARE COMPATIBILITY:
See the appendix for details.
Though most reports say the Consensys PowerPorts board is fine for UUCP use,
at least two USENETters have reported problems with interactive sessions; see
below.
TECHNICAL NOTES:
The X stuff is straight off the MIT X11R5 tape, patchlevel 8.
KNOWN BUGS:
This port probably uses the stock USL 4.0.3 libraries. Thus it probably
has the known bug with sigvec() and may have the rumored bug in the BSD-
compatibility string functions.
One `Andy', mailing from <hooplet@ucsu.Colorado.EDU> says "You should also
blast Consensys for advertising that they provide DOS file system utilities.
They do, but they were written for DOS 2.0! They do NOT work for DOS 5.0..."
Syd Weinstein <syd@dsinc.dsi.com> reports: "The most major [bug in the
PowerPorts support] is delays in various output codes.... Even if not using
the multi-screen stuff, a clear to end of line escape code, and some others,
cause noticable delays in the output. (About 0.1 seconds). It makes running
Elm a real bitch". He is in touch with Consensys about this.
It has been reported on USENET (by Gerry Swetsky <lisbon@vpnet.chi.il.us>
among others) that if you drop off of a PowerPorts line without manually
closing all your sessions, the unclosed sessions may be accessible to the next
person to pick up the line.
Gil Kloepfer, Jr. <gil@limbic.ssdl.com>, managing the Houston UNIX User's
Group's system, says that during interactive use the board frequently does not
handle typeahead properly (this may be related to Syd Weinstein's problems with
EOL delay). He also says he hasn't been able to bring up stable UUCP with the
board.
COMMENTS:
Their UNIX product is an outgrowth of their main line of business, selling
serial boards. It is easy to configure the OS to support the board.
WHAT THE USERS SAY:
I've spoken with one experienced wizard using Consensys and seen a detailed
email report from another. They're happy, although they both warn that newbies
should probably *not* try this at home :-).
On the other hand, Consensys has a dismal reputation on USENET; horror
stories of nonexistent followup on bugs abound. They'll need to work hard to
shuck their take-the-money-and-run image. Better followup on the reported
serial-port board bugs would be a big help. Unfortunately, Consensys's favored
response seems to be to deny that they have a problem.
REVIEWER'S IMPRESSIONS:
These guys are trading off everything else to be the market's price-buster.
They have the toughest support policy of any vendor and obviously don't want to
hear from you once you've gotten past initial boot.
A Consensys marketroid that I spoke with twice while gathering this
information offered to send me an evaluation copy of their system. They were
clearly hoping for some good publicity if I like it. However, I doubt they
like me that well any more...
Consensys explicitly refuses to say how many development engineers they have
on staff. In this and some other matters (such as the way they deal with
allegations of PowerPorts problems) they've adopted a corporate style that
appears defensive, evasive, secretive, and not conducive to trust. I couldn't
make their V.P. of sales understand that this appearance is a serious
liability in dealing with UNIX techies and distinguishes them from the
competition in a distinctly negative way.
NAME:
Dell UNIX System V Release 4 Issue 2.2.
VENDOR:
Dell Computer
9505 Arboretum Road
Austin TX 78759
(800)-BUY-DELL (info & orders)
(800)-624-9896 (tech support: x6915 to go straight to UNIX support)
info@dell.com --- basic Dell info
support@dell.com --- support queries
SOFTWARE OPTIONS:
Basically, there aren't any. You get the development system with all the
trimmings for a lower list than anybody else in the top tier. Whaddya
want, egg in yer beer?
ADD-ONS:
Dell bundles a DOS bridge (Locus 2.2, supporting DOS 5.0) with their base
system. They also include cnews, mmdf, perl, elm, bison, gcc, emacs gdb, Tex,
network time protocol support, and other freeware, including a bunch of nifty X
clients! Also included: the Xylogics Annex server for TCP/IP network access.
FrameMaker is also included, but runs in demo mode only until you buy a
license token from Unidirect.
SUPPORT:
Dell *does* support their UNIX on non-Dell hardware. They are quite
definite about this. They will deal with software problems reported from
non-Dell hardware, but you're on your own when dealing with hardware
incompatibility problems unless you can reproduce the problem on a
Dell PC.
You get 90 days of free phone support on a toll-free number, starting on
resceipt of your registration card (no card, no support). Yearly service
contracts range are $350 per year for the limited license, $500 for the
unlimited.
There are 6 engineers in their first line and 4 in their second-line support
pool.
Dell accepts software problem reports from anyone, Dell or non-Dell
hardware and whether or not they have a support contract. If you don't have
a support contract, don't count on getting a reply acknowledging the report.
Dell maintains a pair of Internet servers (dell1.dell.com and
dell2.dell.com) which hold patches, updates and free software usable with
Dell UNIX.
About upgrades, Dell says "If you have a support contract, the upgrade is
free, unless we've added something with significant royalty burden to us. We
may make a charge at that point. We didn't when we added Graphical Services
4.0 at the introduction of Dell UNIX 2.1. If you don't have a contract, then
the cost is basically Media+Royalty+Admin+Shipping."
FUTURE PLANS:
X.desktop 3.0 will be supported soon. NeWS isn't going to happen at all;
they couldn't get it to work reliability.
Dell has demonstrated a 486 port of NeXTSTEP at trade shows.
Dell is going to move to Solaris someday. However, policy is that they're
not going to phase out SVr4 until at least a year after their first *reliable*
version of Solaris, in order to provide an upgrade path.
TECHNICAL NOTES:
The big plus in the Dell code is that they've fixed a lot of the annoying
bugs and glitches present in the stock USL tape.
The installation procedure has been improved and simplified. You can
install Dell UNIX through your network from another Dell box once you've booted
the hardware with a special disk provided.
Both benchmarks and anecdotal reports make them significantly faster than a
stock USL system. Interestingly, Dell's manager for UNIX development tells me
this is all due to bug fixes and careful choices of some OS parameters.
A source at Dell has asked me to point out that Dell's SLIP can be
set up, configured, and stopped while UNIX is running; some other
versions (such as SCO's) require a reboot. However, others claim that
SCO's can actually be reconfigured without a reboot and that the SCO
*manuals* are at fault here for misleading people.
Dell device drivers are *very* unlikely to work on other SVR4 versions.
Dell includes some kernel extensions (not required, so other SVR4 device
drivers should work) to make life in support a little easier. A program
called showcfg will list all recognised device drivers and the IRQ,
I/O address, shared memory and so on. The device driver has to register
this info. Dell has told USL how to do this, it's up to them when or even
if they want to use this in a future release.
Dell device drivers are also auto configuring, for the most part. Check out
/etc/conf/sdevice.d/* and see how most of the devices are enabled, but with
zeroes in all fields for IRQ, I/O and memory. Those are autoconfiguring
drivers. Dell thinks that this makes life much easier; you only need to set
one of the configurations that they probe for! The device registration helps
this, by eliminating possible overlapping memory or I/O address usage. (On the
other hand, idconfig(1) is no longer helpful, when I/O, IRQ and mem are all
zero). The 2.2 release adds a utility `setcfg' which can be used to remove
unneeded drivers, shrinking the kernel.
Dell UNIX also has drivers for the Dell SmartVu found on some machines (a
little four character LED display on the front panel). By default this shows
POST values, then disk accesses, finally "UNIX" when running and "DOWN" when
halted. You can write to the device.
Dell's SCSI tape driver includes ioctls to control whether hardware
compression is used.
Some Dell systems have a reset button. On the Laptops these are wired
directly to the CPU. On the desktop and floor-standing systems Dell UNIX can
catch the interrupt; it's used to do a graceful (init 0) shutdown. Other
UNIXes will do a processor reset when the button is pushed.
About 95% of 2.2 was built using GNU cc for a significant performance
improvement over pcc.
KNOWN BUGS:
Uucico fails when sending more than 12 files to another machine. Fixed
in 2.2; a patch is available free from Dell for earlier versions.
Performance monitoring of uucp transfers doesn't work. Creating
/var/spool/uucp/.Admin/perflog results in uucico logging statistics to the file
correctly. However, using uustat -tsysname results in either a memory error or
you just being returned to the shell with no output. This bug is known to
Dell and being worked on now.
Merge is seriously buggy in many areas. It takes ages to start up in an
xterm and then sometimes crashes in the process. Attempting to use its
simulated expanded memory results in the system becoming slowly corrupted which
later results in virtual terminals disappearing and the system gradually
locking up. Really fun stuff! And it can only cope with 1.44M discs. These
are generic Merge problems, not really Dell's but Locus's fault.
There are some dropped stitches in the supplied USENET tools. The server
has been compiled for a dbm history file while c-news has been compiled for
dbz. With nntpd this only shows on the ARTICLE <message-id> command which
either returns that the article with that id can't be found or crashes the
server. Also, they forgot to include the nntpd manual page or nntpxfer. A
Dell source thinks these things have been corrected in 2.2.
HARDWARE COMPATIBILITY:
Dell doesn't maintain a list of non-Dell motherboards and systems known to
work. And they're not willing to talk about the list they don't maintain,
because it would amount to endorsing someone else's hardware.
Dell promises that you can bring its UNIX up on any Dell desktop or tower
featuring a 386SX or up (it's hard to get the product on to the notebooks).
Notebooks can't drive a QIC tape and there aren't drivers for the pocket
Ethernet or token-ring adapter.
Jeffrey James Persch <using a friend's account> reports that he couldn't
get the X supplied with Dell UNIX 2.1 to work with a Microsoft bus mouse hooked
to the mouse port on a Compaq 486/33M or Systempro.
Andrew Michael <Andrew.Michael@brunel.ac.uk> says "If you're buying Dell
UNIX for non-Dell hardware, first try booting the Dell floppy on it. From
experience, some BIOS ROMs cause Dell SVR4 to lock up at the point where it
tries to talk to the hard disk. If it gets to the point where it asks you
whether you want to install or not you can be pretty sure that all is well. An
AMI or Phoenix BIOS is OK; be careful of anything else."
See the appendix for more.
COMMENTS:
Dell sells hardware, too :-). They are, in fact, one of the most successful
clonemakers, and will cheerfully sell you a Dell computer with SVr4 pre-
installed. Their systems are expensive by cloner standards (with as much as a
$1000 premium over rock-bottom street prices) but they have a rep for quality
and reliability their competition would probably kill for.
You can get Dell product information by sending an email request to
info@dell.com.
WHAT THE USERS SAY:
Most people who've seen or used it seem to think pretty highly of the
Dell product, in spite of minor problems.
A user in England observes: "Dell is the only firm that I found supplying
Unix at the real monetary exchange rate, not the usual computer pounds=dollars
nonsense. In the UK the 2 user version costs 699 pounds, which is pretty close
to the US price in dollars. For those of us who don't live on the left-hand
side of the pond (there are a few of us!) that's a distinct advantage." He
adds "Dell's UK support is pretty good. Not as good as Sun, but then you don't
pay as much! From previous experience, SCO support in the UK is, well, pretty
non-existent."
REVIEWER'S IMPRESSIONS:
Right now, I'd have to call Dell the market leader in SVr4s. The
combination of low price, highest added value in features, and reputation for
quality makes them very hard to beat.
The only serious negative I've seen is that their support system seems to be
very badly overloaded, so you can end up on hold for a while when calling. The
techs themselves are sufficiently cranked about this that they'll complain of
understaffing and corporate shortsightedness on the phone to a stranger.
Dell has recently doubled their support staff and fixed a bad bug in their
call-handling system that was freezing the queue for up to two hours at a
time. This will certainly help matters.
On the other hand, Dell's UNIX development manager responded to the first
issue of this FAQ with about three hundred lines of intelligent, thoughtful and
extremely candid comment, including a whole pile of hardware-compatibility info
and a number of excellent suggestions for improving the FAQ. He has
continued to send voluminous, factual feedback to later issues --- an example
other UNIX vendors would do well to emulate!
NAME:
ESIX System V Release 4.0.4
VENDOR
Esix Computers
1923 E. St. Andrew Place
Santa Ana, CA 92705
(714)-259-3020 (tech support is (714)-259-3000)
uunet!zardoz!everex!esixtech
ADD-ONS:
None.
SOFTWARE OPTIONS:
ESIX can be bought in the following pieces:
Unlim 2-user
Base system 784 384
Base system + Networking 866 396
Development system 131 N/A
GUI module (X, Motif, Open Look, X.desktop) 610 380
Note that the base system without networking cannot be upgraded to the
base system with networking; you'd have to replace at full cost.
SUPPORT:
Purchase buys you unlimited free phone support. However, be warned that
there are only two engineers assigned to the job and they are swamped.
Esix offers a support BBS at (714)-259-3011 and 3013 (the 11 line
has a Trailblazer on it). They plan to bring up an Internet server in
the near future.
FUTURE PLANS:
They don't plan to support DOS Merge because it's still horribly buggy.
Later in '92 they plan to release a multiprocessing UNIX.
TECHNICAL NOTES:
Stephen J. Friedl and D'Arcy Cain <darcy@druid.uucp> have written a device
driver for Everex's STEP systems that can control the LED array on the front of
the box.
Relative to 4.0.3, 4.0.4 includes numerous bug fixes, a rewritten SCSI
driver, and better SCO binary compatibilty. The GUI package is significantly
different, changing from a home-grown ESIX implementation of X to a licenced
implementation of AT&T's xwin implementation (with ESIX support for additional
video cards added in.
HARDWARE COMPATIBILITY:
See the appendix for details. ESIX supports an unusually wide
range of peripherals.
They advertise support for the Textronix X terminal.
No one has reported any incompatibility horror stories yet.
KNOWN BUGS:
According to Esix, this port uses the stock USL 4.0.3 libraries. Thus it
must have the known bug with sigvec() and may have the rumored bug in the BSD-
compatibility string functions.
COMMENTS:
Another subsidiary of a clonemaker (Everex). They don't sell bundled
hardware/software packages yet.
Esix will sell you manuals troffed off the SVr4 source tapes for somewhat
less than the cost of the Prentice-Hall books. The content is almost identical
but the organixation into volumes a little different.
Unlimited free support sounds wonderful, and might be ESIX's strongest
selling point. However, ESIX users on the net have been heard to gripe that in
practice, you get the support you've paid for from Esix --- that is, none.
That isn't at all surprising given Esix's staffing level. If this guarantee is
to be more than a hollow promise, their technical support has to get more
depth.
Evan Leibovich <evan@telly.on.ca> is a long-time netter who makes his living
as a consultant and owns an Esix dealership. He says you can get ESIX at a
substantial discount from him or other dealers, also that dealers are supposed
to do first-line support for their customers (which he does, but admits other
dealers often fail to). Evan is obviously devoted to the product and probably
the right guy to email first if you think you'd be interested in it.
WHAT THE USERS SAY:
Ron Mackey <rem@dsiinc.com> writes "In general, we are pleased with ESIX.
We still have problems driving the serial ports at speeds greater than 9600
baud. We also still see occasional PANICs. These appear to be related to
problems with the virtual terminal manager." This may be the generic USL asy
problem again.
William W. Austin <uunet!baustin!bill> writes "The support from Esix seems
to be usable if (a) you are a hacker, (b) you know unix (sVr4 internals help a
lot), and (c) you get past the sales guy who answers the help line (Jeff
[Ellis] is *very* helpful). If I were a computer-semi-literate, commercial
user who only wanted his printer to work, etc., I might be up a creek for some
problems (no drivers for some boards, no support for mouse tablets, etc., but
that's what VARs are for). All in all, the support is at least a little better
than what I expected for free -- in many cases it is *far* better than the
support I got from $CO (is SCO really owned by Ebenezer Scrooge?)"
A longer appreciation from Ed Hall <edhall@rand.org>: "I had a problem with
the ESIX X server. I got through to technical support immediately, and was
promised a fix disk. The guy on the phone was actually able to chat with on of
the developers to check to see if the disk would solve the problem. The disk
came four days later."
"On the other hand," he continues, "I get the feeling that ESIX has only
made a mediocre effort to shake out the bugs before releasing their system-- or
even their fixes. For example, they `repaired' their X server, but the new
server only ran as root (it made some privileged calls to enable I/O
ports)--they quickly had to release a second update to fix this new problem.
They obviously fixed a lot of things in the new server, and performance is
improved quite a bit as well, but the stupid error they made in the first
"fixed" version should have been found with only the most minimal of testing."
"They've done some work on the serial driver, but there are still some
glitches (occasional dropped characters on a busy system at 38400bps, and a
real doozy of a problem--a system panic--when doing simultaneous opens and
ioctl's on a tty0xh and ttyM0xh device. This latter problem was due to my
using the M0xh and 0xh devices improperly, but panics are inexcusable. No idea
if this is a SYSVR4 problem or due to their fixes.)"
"So my impressions of them are mixed. Perhaps I just lucked out in geting
such rapid response on my support call, but I was impressed by it nonetheless.
On the other hand, their QA needs work..."
REVIEWER'S IMPRESSIONS:
The tech I spoke with at Esix seemed knowledgeable, bright, and very
committed to the product. Nevertheless, when I asked what he thought
distinguished ESIX from the competition, he had no answer.
This reinforced the feeling I got from the spec sheets that Esix has kind of
an also-ran mentality, with no market strategy or clear priority for improving
SVr4 that positions it against its competition. It doesn't have Dell's
steak-with-all-the-trimmings appeal, it's not pushing price like Consensys or
support quality like UHC or performance like Microport. (I'm told that
at one time, Everex was the price leader).
When I asked Esix's chief marketroid about this, he said that he thinks
ESIX's best asset is that the product isn't going to go away, and muttered
unkind things about the possibility that Dell would deep-six their SVr4 in
favor of Solaris 2.0. This does not a long-term strategy make.

SOFTWARE OPTIONS:

SUPPORT:
30 days of support free with purchase.
1 year of fax/email support is $299, 1 year of phone support is $599.
FUTURE PLANS:
They expect to upgrade to Motif 1.2 and X11R5 Summer '92. No plans for
4.0.4 yet.
HARDWARE COMPATIBILITY:
They've promised to email me a list of hardware known to work, which
will appear in a future posting.
They decline to release information on hardware known *not* to work
for fear of offending vendors.
KNOWN BUGS:
This port probably uses the stock USL 4.0.3 libraries. Thus it probably
has the known bug with sigvec() and may have the rumored bug in the BSD-
compatibility string functions.
The DOS support is only 2.0-compatible (< 32-meg DOS partitions).
COMMENTS:
Another outfit offering stock USL real cheap. They were actually the first
to try this (in Fall '91) and were the price leader until Consensys blew past
them.
These guys really want to sell you preinstalled UNIX on their clone
hardware. Configurations range from $1349 to $5599 and look like pretty
good value.
WHAT THE USERS SAY:
I have one experience report from Ray Hill, <hill@ghola.nicolet.com>, who's
been running MST on a 486 for a month or so. He says it works; elm, cnews, and
trn are up, so standard UNIX sources compile up and work fine. His only
criticism is the relative skimpiness of the printed docs.
Harlan Stockman <hwstock@snll-arpagw.llnl.gov> writes "MST has been very
helpful at every step of the way; phone and e-mail support have been timely."
Geoffrey Leach <geoff@ibmpa.awdpa.ibm.com> warns that some of the files
(specifically, socket library headers) necessary to build X11R5 are bundled in
the networking option --- this may meen you have to buy it even if you don't
actually intend to network any machines.
REVIEWER'S IMPRESSIONS:
Anyone who's been to a hobbyist computer expo in the last five years knows
that the low-price clone-hardware market is full of small, hungry companies run
by immigrants, often family businesses. Their English is sometimes a little
shaky but (in my experience) they're honest and their product is good, and
their prices are *real* aggressive.
MST seems to be one of these outfits. Right now they're eclipsed by
Consensys, but Consensys's promo prices are *so* low that they may be taking a
net loss to gain market share. In any case, two super-low-cost-vendors are
much more effective pressure on the upper tier than one --- long may MST
flourish.
NAME:
Microport System V Release 4.0 version 4

108 Whispering Pines Drive
Scotts Valley, CA 95066
(800)-367-8649
sales@mport.com (sales and product info)
support@mport.com (support)
SOFTWARE OPTIONS:
Networking (TCP/IP, NFS)
Software Development
User Graphics Module (X GUIs)
Graphics Development Module (X toolkits + man pages).
DOS Merge
ADD-ONS:
A few freeware utilities are included, notably kermit(1) and less(1).
They include a single-user copy of a program called `JSB MultiView'. It's a
character-oriented desktop program that front-ends conventional UNIX services
for character terminals and also provides a calendar service and
pop-up phone-book. It's something like a character-oriented X windows; each
on-screen window looks like a terminal to the application.
SUPPORT:
The base price includes printed docs. This is effectively the same content
as the Prentice-Hall SVr4 books; both are troffed off the SVr4 source tapes.
They have been very lightly edited for the Microport environment.
The base price includes 30 days or 1 year of phone support respectively
depending on whether you bought the base or complete system. Support is
said to be excellent for serious problems, not so good for minor ones (this
is understandable if one assumes their support staff is very good but
overworked, a hypothesis which is plausible on other evidence).
They have a support BBS at (408)-438-7270 or 438-7521. However, the level
of activity is low; one customer said (late February) that they hadn't put
anything useful on it in six months (Microport responds that they've
been too busy hammering on r4 to spend lots of energy on it).
FUTURE PLANS:
DOS Merge will be folded into the system soon.
Also working on improved performance for the Adaptec 1742 and other SCSI
controllers, expect that in May.
Microport believes they have a lead in multiprocessing UNIX and intend to
push it.
File-system support for CD-ROMs is coming.
HARDWARE COMPATIBILITY:
See the appendix for details.
Math co-processors: Cyrix 20/25/33, Intel 80387 20/25/33, Weitek.
No one has reported any incompatibility horror stories yet. Bernoulli boxes
and Irwin tapes won't fly, but who cares.
TECHNICAL NOTES:
When I asked what differentiates Microport from the other SVr4 products,
the answer I got is "performance". The Microport people feel they've put
a lot of successful work into kernel tuning.
And, indeed, benchmarks from independent sources show that Microport's
fork(2) operation is quite fast. Other vendors show about 60 forks per
second on the AIM Technologies SUITE II benchmarks; Microport cranks 80.
This is the most dramatic performance difference the AIM tools reveal
among any of these products. Microport's other benchmark statistics
are closely comparable to those of its competitors.
Microport also offers a symmetric multiprocessing SVr4 which will run on the
Compaq SystemPro, the ALR PowerPro, the DEC 433MP, and the Chips & Technologies
Mpax system.
Microport has moved the socket headers and libraries necessary to build X
out of the networking option package into the development system, so you
don't have to buy an extra module to hack X.
KNOWN BUGS:
According to Microport, this port uses the stock USL 4.0.4 libraries. Thus
it must have the known bug with sigvec() and may have the rumored bug in the
BSD-compatibility string functions.
David Wexelblat reports that "Microport's enhanced asy driver does not work
correctly (or at all) for hardware flow control - you can't open the ttyXXh
devices under any circumstances. This was true in 3.1, and is still true in
4.1. The good news is that SAS (Streams-FAS) works fine for modems. But SAS
won't work with the AT&T serial mouse driver. So I've got asy on my mouse port
and SAS on the other one on my dumb-card. [...] Microport is still prone to
silly errors. The Motif development system, which is described in the release
notes as being included with the Motif runtime system in the 'complete'
package, is in fact missing from the tape. They have it available seperately,
but I had to call them to get it. The 'pixed' application for X.desktop 3.0 is
compiled with shared libraries that are not included with the release. Hence
it does not work. I had to call them about this, too."
COMMENTS:
These people sold a lot of shrink-wrapped UNIXes years ago before going
chapter 11. They're back, leaner and meaner (with a total staff of just
15).
Microport says it's primarily interested in the systems-integration market,
where customers are typically going to be volume buyers qualifying for deep
discounts. Thus, they're relatively undisturbed by the certainty that their
high price point is losing them sales to individuals.
WHAT THE USERS SAY:
I've received one good comprehensive experience report, largely favorable,
from David Wexelblat <dwex@mtgzfs3.att.com>.
REVIEWER'S IMPRESSIONS:
Microport is a small, hungry outfit with a lot to prove; they've already
gone bust once (I was a customer at the time :-() and they haven't yet
demonstrated that they've got a better strategy this time out.
They're perhaps a mite too expensive for the support quality they can offer
with less than fifteen people, and kernel-tuning isn't going to win them a
following on hardware that every year swamps those tweaks with huge increases
in speed for constant dollars. It may be that they're counting on the
symmetric-multiprocessor version to be their bread-and-butter product; there,
at least, they're offering something that is so far unique and promises
performance levels unattainable with conventional hardware.
And, like UHC, they have techies answering the phones and the techies have a
clue. This certainly improves them as a bet for wizards and developers. If
multiprocessing is important to you, and/or you're looking for a small outfit
where you can develop personal working relationships with the tech people who
matter, Microport might be a good way to go.
They've offered to send me a copy of their OS gratis for review and
evaluation purposes.

HARDWARE COMPATIBILITY:
See the appendix for details.
The asy driver in version 2.0 won't talk to the NS16550AFN UART, which
is supposed to be pin-compatible with the standard 16450.
KNOWN BUGS:
This port probably uses the stock USL 4.0.3 libraries. Thus it probably
has the known bug with sigvec() and may have the rumored bug in the BSD-
compatibility string functions.
COMMENTS:
They claim that according to USL they have the largest installed base of
SVr4 customers, and to have been first to market with a shrink-wrapped
SVr4 (in 1990).
UHC also claims to have performed and maintained IBM's official UNIX port
for the MicroChannel machines.
A subsidiary of Anam, "a holding company with a diversified portfolio".
WHAT THE USERS SAY:
The only comment I've yet seen on UHC itself was an extended description of
a successful installation by a satisfied netter. He made it sound like a good
solid product.
I have one absolutely incandescently glowing report on UHC support from a
developer named Steve Showalter <shwasl@Texaco.COM>. He says: "We've been
running UHC's OS for about a year now...been EXTREMELY happy with it. The
support we receive is without a doubt, the finest we have received from any
vendor."
REVIEWER'S IMPRESSIONS:
I found both the people I talked to friendly, candid, technically
knowledgeable, and willing to answer sticky questions. I came away with a very
positive impression of the outfit's operating style.
There are experienced UNIX developers who value dealing with a small,
responsive outfit where they can develop good working relationships with
individuals. UHC says it likes to sell to wizards and might be a good choice
for these people.
The second time I called (*after* I'd formed the above impressions) one of
their guys offered to trade me a copy of UHC UNIX with all the trimmings for an
autographed copy of _The_New_Hacker's_Dictionary_. So they have taste, too.
I'm too ethical to let this sway my evaluations, but not too ethical to take
the software... :-)
NAME:
BSD/386
VENDOR:
Berkeley Software Design, Inc.
3110 Fairview Park Drive, Suite 580
Falls Church, VA 22042 USA
(800)-800-4BSD
bsdi-info@bsdi.com
SOFTWARE OPTIONS:
None. You get an unlimited user license, binaries *and sources*
for the entire system. What more could you want?
SUPPORT:
The purchase price include 60 days of phone support.
A telephone-support contract is $1500 per year; email-only support is
$500/year. Either kind includes upgrades.
FUTURE PLANS:
The current release (0.3) is a fairly stable beta. Production release is
planned for June 1992.
Capability to run SVr3.2 binaries (including SCO binaries), 3Q92.
They intend to add a DOS bridge by the end of '92.
HARDWARE COMPATIBILITY:
See the appendix for details. New drivers are being added all the time.
Multiport serial boards aren't supported (they're working on it).
The Orchid graphics co-processor is not supported.
TECHNICAL NOTES:
Alone among the 386 UNIX versions described here, this version is *not*
based even in part on USL code and has no AT&T license restrictions. Rather,
it derives from Berkeley UNIX (the CSRG Networking 2 release, somewhere between
4.3 and 4.4).
Many of the BSD/386 tools, including the compiler, are GNU code.
This system's libraries, header files and utilities conform to X3J11,
POSIX 1003.1 and POSIX 1003.2 standards.
COMMENTS:
What these people are trying is audacious --- something functionally like
the SVr4 merge, but starting from a ported BSD kernel and with System V
compatibility hacks, rather than the other ways. By all accounts the product
is in far better shape right now than one would expect for a beta pre-release,
which argues that the developers have done something right.
WHAT THE USERS SAY:
The few who've seen this system display an evangelistic fervor about it.
REVIEWER'S IMPRESSIONS:
I expect this will become a hackers' favorite.
All this, and sources too...I salivate. I am tempted. Not sure I'm ready
to change OSs at the same time as I switch machines, though. SVr4's got better
continuity with the 3.2 I'm running now. Ghu, what a dilemma!
When I mentioned that I'm doing elisp maintenance for GNU EMACS these days,
Rob Kolstad, one of the principal developers, offered me a copy and a year
of support if I'd field their (so far nonexistent) EMACS problems.

and freeware adapted for the system
FUTURE PLANS:
They plan to move to OSF/1 this year. X11R5 and Motif support are
also in the works.
HARDWARE COMPATIBILITY:
See the Appendix for details.
Color X windows is supported on VGA boards via extended 8-bit color mode.
Toshiba and Toshiba-compatible floppy drives and controllers work.
All current motherboards tested have worked. There were a few problems with
early Compaq DeskPros. They add "Please note that we do not support the
microchannel bus, EISA extended modes, IBM PS2, and some NCR machines. We are,
however, considering new devices so let us know your interests!".
TECHNICAL NOTES
This product is essentially a 4.3 port built on the Mach project's
microkernel technology. This is a truly nifty architecture which builds a
4.3BSD-compatible kernel out of a collection of communicating lightweight
processes. The distinction between user and kernel mode almost vanishes, and
things like the schedular and virtual-memory manager which are normally
embedded deep in the kernel become semi-independent, modifiable modules.
COMMENTS:
Very appealing for the educational market --- lets CS students and hobbyists
tinker creatively with the guts of UNIX in a way that would be impossible under
more conventional UNIXes. It's not clear who else will be interested in this.
WHAT THE USERS SAY:
Eric Baur <ecb@ventoux.assabet.com> writes:
"The system is a very faithful emulation of BSD43 on top of Mach. For our
purposes it is a super deal. For about $2000.00 in hardware and $995.00 in
software we have a Mach development platform that integrates almost seamlessly
into our network development environment. As a general-purpose UNIX (whatever
that means) Mach386 gives up a lot in features to the System V vendors.
(Virtual terminals, DOS emulation, etc etc) For the home hacker, except for
UUCP problems it seems like it would be a good deal. You obviously could never
run "shrink-wrapped" software, but most public domain and GNU stuff should port
easily."
Mark Holden <l00017@eeyore.stcloud.msus.edu> adds "Mt. Xinu's tech support
is absolutely top-notch, and I've found them quite willing to deal with matters
even after the official support runs out. [...] Not that Mach386 is without
its quirks. I've had problems getting a Western Digital ethernet board to
work correctly, and things required a fair bit of tweaking to set things on a
smooth course, but then I've never worked with a BSD that didn't."
REVIEWER'S IMPRESSIONS:
Right now, this product is a solution looking for a problem --- a solution I
find technically fascinating, to be sure. But even the company admits to not
being sure who its market is. I wish 'em luck.
KNOWN BUGS:
From Eric Baur <ecb@ventoux.assabet.com>: "I have not been able to
get the supplied uucp to work when calling a telebit modem. The
connection is established but the Mach end hangs up and exits without
any indication why. Taylor uucp ported in about 1 hour and works
~fine. There is no support, however, for bi-directional lines if you
use the Taylor uucp. The uucp supplied with the system has the
gawd-awful acucntrl hack, but I don't know if it even works. [...]
Overall I remain very pleased with Mach386. [...] It has yet to
manifest any truly bad behavior. No panics - no hangs. It interacts
flawlessly with our network of Suns. NFS and X are very robust. I
would ditch my System V at home and buy Mach386 is a minute if I could
get bi-directional serial lines to work."
In fact, it does appear that one can get bidirectional UUCP to work.
David Brown <dbrown@ucsd.edu> testifies that this can be done without
using the acucntrl hack.
V. HARDWARE COMPATIBILITY TABLES
These tables summarize vendor claims and user reports on which hardware will
work with which port.
To save space in the tables below, we use the following *one-letter*
abbreviations for the OS ports:
S SCO UNIX version 3.2.4
C Consensys UNIX Version 1.2
D Dell UNIX Issue 2.1
E ESIX System V Release 4.0.4
M Micro Station Technology SVr4 UNIX
P Microport System V/4 version 4
U UHC Version 3.6
B BSD/386 (0.3 beta)
X Mach386
A `c' indicates that the hardware is claimed to work in vendor literature.
A `y' indicates that this has been verified by a user report.
A `.' indicates that whether this combination works is unknown.
An `n' indicates that the vendor advises that the combination won't work.
A `*' points you at footnote info.
A blank column indicates that I have received no vendor info on the
hardware category in question.
The following general caveats apply:
* All ports support EGA, VGA, CGA and monochrome text displays.
* All ports support generic ISA serial-port cards based on the 8250 or 16450
UART. According to the vendors, the asy drivers on Dell, Esix, Microport,
BSD/386 and Mach386 support the extended FIFO on the NS16550AFN UART chip.
Indeed, Dell tech support will tell you this feature was present in the
base USL code. UHC says its 2.0 drivers *don't* talk to 16550s but
says that will be fixed in March '92. A user reports that SCO has
supported the 16550 since 3.2.2.
* I have not bothered listing ordinary ST-506/IDE/RLL drives, though lists
of them are given in vendor literature. This is a very mature commodity
technology; anything you buy should work with one of the supported
controllers unless it's defective.
* Vendors' supported hardware lists are not models of clarity. Some iterms
may be listed under a couple of different names because I don't know that
they're actually the same beast. I have been very careful not to make
assumptions where I am ignorant; thus, some hardware may appear less
widely supported than it actually is.
* These tables are grossly incomplete.
All the SVr4 systems inherit support for a fairly wide range of hardware from
the base USL code (version 4.0.3 or 4.0.4). This includes:
* All PC disk controllers (ESDI, IDE, ST-506 in MFM and RLL formats).
* The Adaptec 1542B SCSI adapter. Note: you'll have to jumper your
SCSI devices to fixed IDs during installation on most of these.
* Western Digital's 8013EBT Ethernet card, and its equivalents
the WD8003 and WD8013. SVr4v4 adds the 3Com 3C503.
* VGA adapters in 640x480 by 16 color mode.
* "C" protocol serial mice like the Series 7 and Series 9 from Logitech and
the PC-3 mouse from Mouse Systems (however, we've had one report of an
ostensible PC-3 clone called the DFI200H not working). See the "HOT TIPS"
section for details.
SCO UNIXes from 3.2.2 up and ODT 1.1 also support all these devices.
If you can fill in any of the gaps, or convert a `c' to `y', send me email.

Notes:
* These two tables probably way *understate* the compatibility of most ports.
Most ISA or EISA motherboards will work with all of them. However, Jeff
Coffler <coffler@jeck.amherst.nh.us> reports: "I couldn't get the Cache
Computer CPU board to work at all with Dell UNIX, even though they claimed
they work with SCO. Flaky, timing-related failures."
* A source at UHC describes the DTK boards as "dogshit" --- he says they
generate a lot of spurious interrupts that DOS is too cretinous to be
bothered by but which completely tank UNIX. He says DTK seems uninterested
in fixing the problem. Other correspondents confirm that this has been
going on for several years. Avoid these boards till further notice.
* Dave Johnson <ddj@gradient.com> reports that since upgrading from a 386 to
an Eteq 486, they've had lots of UHC random panics due to page faults in
kernel mode. UHC is looking into this.

In this table, an `SVGA' resolution code signifies the following resolutions:
1024x768 at 2 and 16 colors, 800x600 at 2, 16, 256 colors, and 640x480 at 2,
16, 256 colors. SVGA+ adds 1280x1024 at 2 or 16 colors. Some non-interlace
boards are marked with N.
Caveats in interpreting the above table:
* All super-VGA cards will work at VGA resolutions and below (that is, resolu-
tions up to 640x480 in 16 colors).
* This list is not exclusive. Many (perhaps even most) dotted combinations
will work. UHC claims that any SVGA based on an ET3000, ET4000, Paradise
or Genoa chip-set will fly; Dell echoes this with regard to ET3000,
ET4000, WD90C0xx cards, and the same is probably true of all other vendors.
* The Renaissance GRX-II is the same board as the Appian Rendition II; the
company changed its name.
* Consensys's list is just MIT's list of cards certified to work with X11R5;
Consensys is careful to note that they haven't tested all these themselves.
* An ESIX reseller says all the TIGA34010-based SVGA cards are pretty much
alike and ESIX will drive any of them. ESIX also supports 720x348
resolution on cheap Hercules-compatible monochrome tubes, and the Everex
UltraGraphics display at 1664x1200 resolution.
* UHC says they expect to have the drivers for the ATI WonderCard in place by
mid-March.
* Beware the Trident and Oak chipsets. Many clone vendors bundle these with
their systems because they're cheap, but they break the Roell server and
some other X implementations. Also, they appear to argue with the WD8003EP
net card, and no re-arrangement of the jumpers seems to fix it.
* Third party server technology from companies like MetroLink can support
higher performance, higher resolution TIGA and proprietary technology.
* Dell's 2.2 adds X11R5 servers for VGA 640x480, 800x600 and for the Tseng
Labs ET4000 and WD90C11 in up to 1024x768 16 or 256 colour. Appian
Rendition II (formerly Renaissance) for 1024x768 TIGA 34010. Highest
performance from the ATI Ultra 1024x768 256 colour, and highest resolution
from the 1280x1024 256 colour JAWS (Dell proprietary card developed in
association with Lotus and MicroSoft)
* The Orchid ProDesigner IIs (top speed 80 MHz, not the 75MHz version) works
with both X386-1.2D and X386-1.2E (beta). It works ok with the ESIX 4.0.3
X11R4 stuff at any resolution under 1024x768. But the driver does *not*
work with 1024x768 (timings are way off). The vanilla ProDesigner II does
work correctly with both the X386 and the Esix X11's (R5 and R4,
respectively). Note: this info may change in ESIX 4.0.4, which uses a
different X.

Notes:
* See the discussion of mice at the beginning of this section for details.
* BSD/386 says it supports all 1200-9600 baud serial mice, specifying Logitech
as an example. This is probably true of all vendors.
* The MouseMan and TrackMan require a patch obtainable from SCO to run under
ODT 1.1; they're fully supported in 2.0.
* X11R5 (X386 1.2) supports all of the known mice on SVR4 in a native mode,
bypassing the mouse driver. This wasn't true with X11R4 (X386 1.1b).
So if you're using X386 1.2 exclusively, you can use (say) a MouseMan
regardless of which SVR4 you're using.
* Dell 2.2 includes an auto-configuring mouse driver that's supposed to
work with about anything. Non-factory-installed 2.2s may require a
patch from support to handle the Logitech Mouseman.

*not* assume that a board is supported on a particular port unless the
vendor explicitly says so.
* MtXinu says they have *no* multiport support right now.

requires a full SCSI-2 tape drive.
* BSDI says they plan to support the 1740 in native mode in the production
release.
* The BusTek 542 is a clone of the Adaptec 1542. At least one respondent
thinks it works better and faster with the Adaptec drivers than the
Adaptecs do! The BusTek 742 has more complicated antecedents; it's an
EISA clone of the 1542, not necessarily compatible with the 1742.
* There's a known bug in the Adaptec 1742 firmware that produces hangs
when it's used with certain SCSI tape drives, including the popular

* All SVr4s inherit USL support for QIC-02, QIC-36 1/4", or SCSI tape
interfaces, using QIC-24 (9-track, 60MB), QIC-120 (15-track, 125MB) or
QIC-150 (18-track, 150MB) formats.
* A user says of Dell: it appears that anything using Wangtek QIC02/QIC36
controllers works; this should include the Wangtek 525MB, Cipher ST150S2,
and Archive 2150S drives.
* UHC specifies the following tape controller/drive combinations: Wangtek
PC-36 + Wangtek 5099-EN, Everex 811 + Wangtek 5150-EN, Bell Tech + Wangtek

* UHC claims that Any floppy tape supporting the QIC-107 physical and QIC-117
logical interface specs and QIC-80 or QIC-40 recording formats should work.
This is probably true of other vendors as well.
* BSDI says it supports any Wangtek 1/4" standard 3M streamer with a
QIC-02 or QIC-36 interface.
* Floppy tapes don't work on Dell; USL provides the support, but it collides
with Dell's code for auto-detecting the density of a diskette.
* SCO's tape compatibility table lists drive/controller pairs; not all drives
listed have been included here. They allege that any QIC-02 drive should
work. Unofficial sources inside SCO claim any SCSI drive ought to work.
* A source at SCO says the CMS Jumbo is neither compatible with QIC40/QIC80
nor Irwin "standards", vendor supplies their own driver which SCO does not
support. CMS is in general fairly UNIX-hostile; don't buy their stuff
if you have a choice.
* The Emulex MT02 is a QIC02 bridge controller for the SCSI bus -- lets you
take an old QIC02 drive and run it on a SCSI bus. It is said to use a
very old version of the SCSI spec; caveat emptor.

VI. FREE ADVICE TO VENDORS:
As a potential customer for one of the SVr4 ports, it's to my advantage to
have everybody in this market competing against one another as hard as
possible. Accordingly, some free advice to vendors, which I'm broadcasting to
all of them and the public so as to put just that much more pressure on each
vendor. :-)
SCO:
You have a serious image problem with many hackers which you've exacerbated
recently by falling behind the SVr4 leading edge and then engaging in what
certainly appears to be an attempt to sucker careless buyers with deceptive
product naming. But the reaction to this wouldn't be nearly so vehement if
it didn't come on top of years of discontent with more technical choices.
There's too much stuff in the SCO kernel and admin tools that's different from
USL and *not better*; too much stuff that raises weird little compatibility
problems that shouldn't be there. Verbum sap.
This different-but-not-better problem is perfectly reflected by the one
thing about the otherwise-excellent SCO documentation that sucks moldy moose
droppings; the rearrangement and renaming of the reference manual sections.
Your technical writers entertain a fond delusion that this helps nontechnical
users, but all it really does is confuse and frustrate techies with experience
on other UNIXes. Lose it.
Everybody but SCO:
SCO's documentation set is to die for (except in the one respect noted
above), and they add a lot of value over the base UNIX with things like ODT DOS
and CodeView. Only Dell comes even close to matching SCO in the nifty add-ons
department, and even they have a lot of room for improvement. If you want to
outcompete SCO, you have to be *better*; this means (at minimum) supporting a
windowing debugger and ISAM libraries and embedded SQL and DOS support that
goes beyond 2.0.
Consensys:
Fix the Powerports bugs everyone is reporting. They're doing you real
damage. Nobody expects real support from an outfit selling at $1000 below
market average, but you've *got* to make your own hardware work right or look
like idiots.
Beyond this, I think you have a serious attitude problem. So far, you're
the only outfit out of nine to refuse to divulge information for the
comparison tables. While you have a perfect right to do so, it smells bad ---
as though you think you have weaknesses to hide. I tried to discuss this with
your VP of sales (Gary Anderson) and got back very little but evasions,
suit-speak, defensiveness, and attempts to divert me from the issues (and I
don't mind admitting that the conversation made me pretty angry and didn't end
very pleasantly). This man's behavior is all too consistent with reports of
Consensys's dismissive behavior towards customers and continued refusal to
acknowledge technical problems.
In this corner of the industry we have a tradition of collegiality, mutual
trust, informality, and candor. If you plan to be here for the long haul, you
need to learn how to work with that rather than fighting it. Behaving like IBM
will only get you hammered.
Consensys and Esix:
Get a real support address. Bang-path accessibility doesn't impress anyone
any more --- in fact, it looks faintly quaint. You guys ought to be
support@everex.com and support@consensys.com to follow the simple and logical
convention SCO and Dell and Microport and UHC have established.
Dell:
Don't get fat and lazy. You've got the lead in the SVr4 market at the
moment and you've got the money and resources to keep it, *if* you use them.
If you staff up your UNIX support operation so customers don't get pissed off
by infinite hold, *and* keep your prices the lowest in the upper tier, no one
will be able to touch you. Don't let Microport et al. get ahead of you in
releases and new technology, and try to reverse that creeping corporatitis (the
no-comment-on-unreleased-products policy is a bad sign).
Everybody but Dell:
Offer all the free software Dell does --- and *more*. All it will cost you
is the media, right? Even if you have to plaster CONTRIBUTED SOFTWARE, NOT
SUPPORTED on it, include perl, elm, bison, gcc, emacs, gdb, mush, patch,
compress, etc on your distribution tapes. Heck, include some *games*.
Nethack, empire, zork, stuff like that. Your engineers use and play with all
this in-house anyhow, yes? And you're selling to guys just like your
engineers. They'll love you for it. Trust me.
Set up a `sales' address to take product queries if you don't already have
one.
A Dell person warns that the kinds of tweaks to the source made by porting
houses can break X/Open (XPG3) conformance. Dell tests every build with VSX
(the X/Open-approved XPG3 test suite) and often finds places where seemingly
innocuous bug fixes cause XPG3 violations. Other UNIX vendors would be well
advised to do likewise.
Everybody but Dell and SCO:
Set up an 800 number for tech support. Support customers hate spending time
on hold, and they hate it like poison when they have to *pay* for the hold
time. The more overloaded your support staff is, the more important this
gets. Verbum sap.
Esix:
You're *boring*. You seem to make a decent product, but there's nothing
I've seen about ESIX that'd make me say "I might want to buy ESIX because...".
Position yourselves; pick something like price or support quality or
reliability or add-on features and push it hard. Warning: if you decide to
push support, *hire more engineers*. Your rep for following up on support
problems is bad enough that your "unlimited free support" ain't much of a draw.
Esix, MST, UHC:
Get 800 numbers for product info, too.
MST:
Set up a support@mst.com alias to your cs address, see above. What would
that take, a whole five minutes? :-)
If you don't start planning for 4.0.4 now, you'll get left behind this
spring and early summer whan all the other vendors move to it.
On present trends, your software prices are cheap enough; you'd probably
get more sales mileage out of pulling down the hardware prices for your
pre-configured systems.
Everybody but MST and Microport:
Set up a `sales' alias to your info and orders email address. A universal
convention for this means just one less detail prospective customers need to
remember.
Microport:
Your complete system is way overpriced relative to what other vendors in the
top tier are selling. If I were a corporate customer, there is no *way* I
could justify spending the $1K or $2K premium over Dell's price --- not when
Dell has the rep it does for quality and features. You aren't offering
anything but a crippled copy of JSB Multiview to justify that premium and
that ain't enough.
There's some evidence that you've got a technical lead on the competition.
Push it; push it *hard*. You're first off the blocks with 4.0.4; keep that up,
be first out with a stable 4.0.5. Market yourselves as the leading-edge
outfit, court the hard-core wizards as their natural ally, detail somebody
who's fluent in English as well as C to listen and speak for you on USENET, and
keep the promises you make there.
UHC:
You've decided to push support; that's good, but follow through by getting
that 800 number. Don't lose those small-company virtues of candor and
flexibility, trade on them. Your policy of having all techs clear up to the
product manager take turns on the support lines is a damned good idea, stick
with it. And I'm sufficiently impressed with what I've heard from your guys
that I think you might be able to fight Microport for the friend-to-wizards
mantle, too. Maybe you should try.
Everybody except BSDI:
BSD/386 includes *sources*. For *everything*. Be afraid; be very afraid.
In effect, this recruits hundreds of eager hackers as uncompensated development
and support engineers for BSDI. Don't fool yourselves that the results are
necessarily going to be unfocused, amateur-quality and safe to ignore --- it
sure didn't work that way for gcc or Emacs. The rest of you will have to work
that much harder and smarter to stay ahead of their game.
BSDI:
Don't you get complacent either. The 386BSD distribution is breathing
down *your* neck...
The most effective things you can do to to seriously compete with SVr4
vendors are: a) emphasize standards conformance --- POSIX, FIPS, XPG3, etc.,
and b) follow through on your support promises. Just another flaky BSDoid
system isn't really very interesting except to hobbyists, even with sources ---
but if it were proven a reliable cross-development platform it could capture
a lot of hearts and minds among commercial software designers.
Everybody:
Do something about your product names! Even the cases that don't appear
to be deliberate deception are very confusing to the customer. If you're
releasing an enhanced 4.0.3 or 4.0.4 that's what you ought to *call* it. I
recommend:
Consensys UNIX Version 1.2 --> Consensys UNIX 4.0.3 revision 1.2
Dell UNIX Issue 2.1 --> Dell UNIX 4.0.3 revision 2.1
ESIX System V Release 4.0.4 --> Esix UNIX 4.0.4 revision 4
MST SVr4 UNIX --> MST UNIX 4.0.3
Microport System V/4 version 4 --> Microport UNIX 4.0.4
UHC Version 3.6 --> UHC UNIX 4.0.3 revision 6
The fact is, all these idiosyncratic version-numbering systems do you no
good and considerable harm. At worst, they make it look like you're trying to
pull a scam by deceiving people about the level of the base technology. At
best, they parade your internal revision number (which conveys no useful
information unless one is an existing customer considering an upgrade already)
and obscure the really important information. Do your product differentiation
elsewhere, in substance rather than nomenclature; it's not useful here.
You're *all* badly understaffed in support engineering, and it shows. Boy
does it show --- in poor followup, long hold times, and user gripes. The first
outfit to invest enough to offer really first-class quick-response support is
going to eat everyone else's lunch. Wouldn't you like to be it?
VII. ACKNOWLEDGEMENTS AND ENVOI
Some of the material in this posting was originally assembled by Jason
Levitt <jason@cs.utexas.edu> of "Open Systems Today". Grateful acknowledgement
is made to him for permission to re-distribute and update this information.
Many netters sent me email contributing technical information, feedback,
and comment. Thanks to all. It's in combinations of individual mission and
collective cooperation like this one that the net really shines, and I'm
grateful to everybody who's worked with me to improve the signal/noise ratio.
The level of cooperation I've experienced from vendors' program managers,
techies and marketing people since the first issue has generally been
outstanding. Particular high marks go to Jeremy Chatfield at Dell, Kristen
Axline at Microport, David Aitken at UHC and Bela Lubkin at SCO, with very
honorable mentions to Jeff Ellis at Esix and Rob Kolstad at BSDI. By
cooperating intelligently with this FAQ, they've done a great job of serving
the market and representing their corporate interests.
One dishonorable mention goes to Gary Anderson, V.P of sales at Consensys
and the only person I've encountered who's behaved like the classic stereotype
of the slippery, stonewalling marketroid. An impression of this kind is
exactly what Consensys needs to solve their credibility problems...NOT!
So far, I've found that the technical merit of each of these eight products
(insofar as I have data to judge; I haven't used any of them yet) seems to
correlate pretty well with the degree of cooperation I've received. I wasn't
explicitly expecting this result, but I'm not surprised by it either.
