Well, the old rule of summaries seems to have hit here:  If you say that
you'll post a summary, then your workload will expand to fill all
available time.

I apologise that this is so late.

The original question was "Which SCSI controller are most people using for
{386,Net,Free}bsd, and are there any problems associated with them?"

The replies were mixed, but most people leaned towards the 154X series.  I
eventually ordered a 1542C board (without the DOS software, cheaper) from
CDW for $189.  The board is the latest rev with the external cabling
patch, and has worked like a champ so far.  I've only used it with my 2
internal drives, but we'll see when I borrow an Exabyte this weekend for
backups.  It's same to say that I've had fewer problems with SCSI than my
old MFM drives.. :)

Anyway, here are the replies I got, in no particular order.  Thanks to all
who replied to my request.  Those of you who asked for a "metoo", it's in
the mail.

ja.

Rules of thumb:
1. Get the newest rev of 1542C. The problem seems much worse on
   the earliest 1542C's. Best way to gaurantee this, is to order it
   from a place that either (1) sells a lot of 1542C's, or (2) get
   it from a place that will have to order one in for you.
2. Get a nice refund policy, just in case.
3. Use *good scsi cabling*. Try to reduce your use of ribbon cable,
   and try to keep your cabling short.

Then you should be ok.

I have an AMI EISA 486/33 motherboard, and an Adaptec 1740 SCSI
adaptor.  Runs fast, never breaks.  I love it.

I am running the Adaptec 1542C on two NetBSD boxes.  I had some
trouble but they were caused by the way my hard disk vendor formatted
my external hard disk prior to shipping.  I almost sent back the 1542
controler until I tried reformatting the HD.  After the reformat both
machines have been working flawlessly.

I have a BusLogic BT 545S card, which is compatible to the 1542B. (I'm normally
skeptical about "compatible" products, but this one worked without any
problems). I don't have exact information about pricing, but I think it is
a little bit cheaper than the Adaptec, so this would be my ISA SCSI controller
of choice again.

As far as I know the 1542 is the only adaptor supported by BSD...
Whatever you do tho, get a busmastering host.

Work hard and prosper,

Go with Buslogic (was Bustek) instead.  Adaptec's "support" is
user-hostile to the point where I don't deal with them any more.

i'm using two aha1742's, and one bustek 542b.

i had some *serious* data corruption problems with a 1542c in
an otherwise-working system.  like, write a bunch of files,
and end up having fsck -n output 7174 lines of output!!!
(LITERALLY!!!)

i'd avoid the 1542c-- the earlier revisions have had several
problems from what i hear.  in addition to the problem
i experienced, there was apparently some problem w/external
cabling, as well...  i dunno how much, if any, of the problems
the later revs have fixed.

I am using and Adaptec 1742c with 386bsd (Which is an EISA board).  I am also
using Julian's SCSI driver (a huge improvement over the as* driver).

I have to put the 1742 into 1542 compatable mode because the boot-blocks can't
deal w/a 1742, but the new SCSI driver puts it back into 1742 mode.

All of this is academic if you don't have an EISA machine though.

Hope this helped,
Brian

I'm running NetBSD with Adaptec 1542B.  I've has NO problems whatsoever
with the controller and NetBSD.  I am in the market to upgrade to 
a Local Bus SCSI-2 Controller though.  I would be interested if you hear
anything about the different types of VL-bus boards.  Thanks for 
sending any info.
