Inside Win98SE's "pure DOS", when I run the DOS utility called
"nvram120.exe", I see the subject line error on screen, and then I
have to reboot. (I wanted to run this utility to see if I could see
if a particular ISA card was installed correctly.)
My mobo is Supermicro P6SBU revision 1.01, and I have flashed the BIOS
to revision 3.1 (latest). The BIOS is called American Megatrends
AMIBIOS setup, version 2.5 (c) 1997.
When I was setting up the mobo (yesterday), I was encountering the
following situations:
1) After installing my PCI cards (one at a time), I noticed that the
BIOS appeared to be "forgetting" some of these cards in the POST
device listing section. (In other words, some cards were being
ommitted from the device listing on reboot.)
2) I also noticed that the "Checking NVRAM..." BIOS POST message kept
saying "...Update OK!", even though between some reboots I had
installed no additional hardware.
3) I also noticed that sometimes a PCI card would be listed as
"Unknown Device", but if I moved the card to a different slot, it
would then be correctly identified as (for instance) "Multimedia
Device".
4) I have also encountered a BSOD when I installed a Diamond 3dfx
card in one particular PCI slot, but then this BSOD would not occur if
I moved the card to a different slot. (Also, this "bad slot" in
question didn't seem to be a bad slot, as I tested it with another PCI
card and it seemed ok.)
To address some of the issues above, in Windows98SE I decided to
Disable NVRAM/ESCD updates inside Plug and Play BIOS properties inside
System/Device Manager. This appeared to fix the perpetual Checking
NVRAM...Update OK! message on every reboot, and also appeared to fix
one or two other resource conflict problems, but not the subject line
problem.
Regarding the BIOS (as described at the top of this message), I've
never seen so many options you can adjust. I'm sure somewhere buried
in these options is a "fix" for every problem I'm likely to stumble in
to, but it's a technical minefield, because I've never used this mobo
before. I tried loading in the BIOS Fail-Safe options to try and fix
the subject line problem, but that didn't work.
ATM, I have this hardware (which all seems to work) -
3 ISA slots = all completely empty now. There *was* a legacy SB16
which worked perfectly, but I removed it to test a legacy Gravis
UltraSound which didn't work, and so it was removed as well.
AGP slot = Matrox graphics card G450
PCI slot 1 (a shared slot with an ISA slot) = empty. (This seemed to
be a bit of a problematic slot, so I've left it empty for now.)
PCI slot 2 = 3dfx card. Was causing BSOD on install, but now seems
fine.
PCI slot 3 = Matrox graphics card G200 (for connecting to above 3dfx
card). Works fine within a "Win98SE hardware configuration profile"
so that I can toggle between this PCI graphics card, and the AGP
graphics card listed above.
PCI slot 4 = Creative PCIAudio ES1371 sound card. Works fine.
Phew, that's it I think. Sorry for the long post! Thanks for any
suggestions at all. Best regards, Robert.
