: As soon as I get the machine back.. :)
Well, I got the machine back. With a BIOS upgrade. No change. :(
Anyway, I captured the boot sequences and also made a logfile from a DOS
-based diagnostic program, so here goes.
First, system description.
Acer, model Altos 7000/V
Pentium 120Mhz processor
256KB L2-Cache
128MB RAM (4x32MB 72-pin SIMMs)
Integral Adaptec AIC7870 controller - resides on PCI bus (pci0:10)
5 EISA slots, 3 PCI slots
Seagate ST15230N Hard disk - 4GB
Sony SDT-4000E DAT drive - 4GB
Matshita CR-504 CD-ROM drive
Video card is either a Diamond STEALTH-64 PCI or a Cirrus Logic CLGD5422
-based card. No differences were observed with either card installed.
The Diamond card has 4MB RAM installed.
System BIOS identifies itself as ACR89E00-M02-950713-R01-K0
Adaptec 7870 BIOS version is 1.11
First, a cold boot from the installation stiffy. The Adaptec BIOS loads,
detects the SCSI devices and all looks happy. The main BIOS banner (shown
when the system looks for a boot device) reports basemem 640KB, Extended
memory 130048KB and Shadow 384KB. Serial ports on 3F8H and 2F8H. Parallel
port on 378H. It also reports the 16KB internal cache and the 256KB external
cache.
Here's the FreeBSD boot - the v and h options specified:-

After this the installation screen pops up on the console. Obviously, this
system is going nowhere with this lot, so I choose Quit and let the system
reboot. Equivalent to a warm boot, I understand.
This time, the Adaptec BIOS doesn't load and the main BIOS banner reports
that there is no external cache. All other indications are as before.
This is what FreeBSD comes up with:-

After this I can go ahead and do a full install (I do it via NFS) and all
appears well. Up to the point where I try to actually boot the system. The
cold boot fails to see the PCI devices and panics when it can't mount the
root filesystem. A reboot (same as the warm boot given above) fails as the
Adaptec BIOS does not get loaded and the system prompts for a boot disk in
the stiffy drive.
I don't know if this is relevant, but a few extracts from a report generated
by PC-CONFIG (a shareware DOS program by Michael Holin) might give some more
information:-

I hope somebody can come up with either a fix for the problems I'm experiencing
or tell me where the problem lies so I can go back to the supplier.
I'm slowly losing my hair over this... and the wife doesn't like the new
balding look. Sorry for the long post but I felt it best to give all the
information that I could lay my hands on.
