My question is: is there a known problem with the following combination
that would cause me to lose one or the other of the AMI or the adaptec
bios after using fdisk from linux? After doing so I cannot boot dos
from a diskette (or from anywhere) but I can boot WinNT and/or linux
just fine.
There follows the boot output. Here are some details of the hardware up front.
scsi disk:
Vendor: Quantum Model: XP34300W Rev: L912
Type: Direct-Access ANSI SCSI revision: 02
controller (onboard):
scsi0 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI) 4.0/3.2/4.0
AIC-7880 Ultra-WIDE (PCI-bus), I/O 0xf800, Mem 0xffafb000:
Bios:
AMIBIOS - no details yet. It's a standard one.
Motherboard:
ATX dual: details unknown at this time.
Processors
twin PPro 200: details unknown at this time.
Kernel:
2.0.25 smp, not that it matters.
Thanks in advance to anyone who has experienced the same symptoms or who
knows of a problem or firmware upgrade that I should have.

: I have just come back from a frustrating evening with a dual PP200
: with an adaptec uw on the MB. You won't get the version numbers from me
: until I get back to the machine in a few days, but I can tell you that it
: boots just fine with the aic78xx controller in the 2.0.25 smp kernel.
: There is a wide quantum (?) on the wide cable and a jaz and a scsi cdrom
: on the other side on the narrow cable, in that order. There is a standard
: ami bios on board. Yecch. WinNT and Win95 were on the machine. I have
: two ide drives in it as well. The ide controller is on a pci card.
: I just repartitioned the extended partition on the scsi drive from linux.
: Bang. I cannot reboot in dos FROM A DOS SYSTEM DISKETTE IN A:. It looks to me
: as though the bios is out to lunch. In contrast, I can boot winnt from the
: ide drive and I can boot linux from a boot diskette. Probably both replace
: the bios. I cannot boot win95 from the IDE. Taking the scsi disk out
: removes the problem. I can boot win95/dos just fine from A: or C: again.
: This is the second time this has happened to this machine. It just came back
: from two weeks at the shop. This time I took it apart. The adaptec was
: TERMINATED both low and high and was in the middle of the chain. That's wrong.
: But I left it because at least winnt and win95 were working that way. At worst
: we are going to lose commands on the bus, not invent crazy ones out of
: nothing. And if the controller goes bang I can take it back and show them the
: smoke and tell them it is their fault.
: The termination was via the cmos, not by jumper. The crunch is that there
: is no ctl-A entrance to the "scsiSelect" utility. You get a dos utility AND I
: CANNOT NOW BOOT DOS UNLESS I TAKE THE DISK OUT. If I do take the disk out
: then I can remove the termination in cmos - not that I have yet - but
: it will leave the chain unterminated for a moment. I'll try it in a few days,
: but I don't think it'll help.
: The problem looks to me as though the adaptec cmos has lost something of its
: bios. As soon as control transfers to it it starts tring to do something with
: the scsi disk, possibly with incorrect geometry (its a 4G). Then dos hangs.
: I know it shouldn't be the case that a boot from A: depends on something on
: F:G:H:, but it appears to be so.
: My question: is there anybody out there who has seen the same crazy behaviour?
: Is there something amiss with:
: adaptec UW on the MB
: dual PPro200
: ami bios
: quantum scsi 4G drive
: as a combination? My bet would be yes. Details later ... meanwhile, please
: mail me if you have a good idea. Do the ami and adaptec bisoses communicate
: right?
: Thanks!
