Hi all,

I have a problem with my p2b-s rev. 1.03 mainboard. I updated the bios
to 1014.003 because I installed a 40GB IDE harddisk. but right after
the flash the onboard scsi controller is somehow deactivated. there is
no "press ctrl+a to..." message at startup anymore. the device itself
and its attached drives isn't present under windows, too. I saved the
old bios (1009) before the flash and I flashed it back, but the
controller is still not available. the scsi enable/disable jumper on
the board is enabled and scsi bios is enabled within "pci & pnp
config".

used hardware:
p3-500
256mb sdram
geforce ddr
350w power supply

please help!

After a BIOS flash, try "Load Setup Defaults" in the BIOS.

If still no positive results, try the "Clear CMOS" procedure,
_unplugging_ the computer before doing the procedure. It is
in the jumper section of the manual - see "Clear real time clock
(RTC)" for details. Apparently the board uses two solder points
and you short them with the blade of a slot-type screwdriver tip.

HTH,
Paul

I'm afraid you have probably destroyed the BIOS on the Adaptec card. There
used to be a warning on the Adaptec site, to remove some of their cards
from particular motherboards, before attempting a motherboard BIOS flash,
because on some motherboards, the addresses used, are the same as those
used by the cards...

Best Wishes

Have you tried pressing ctrl+a while it is booting up? Even if the
message is turned off the controller should still respond to the key
presses.

He can not destroy the bios for the controller. It is built into the
board so it can not be removed. If he flashed the wrong bios, i.e. one
for a P2B rather than a P2B-S the controller wouldn't work but would
work again once the correct bios was flashed.

Second that - I've flashed a gazillion of these boards to 1014b3 and
never seen this problem. The OP *should* see a CMOS checksum error on
the first reboot after flashing (because 1014b3 updates the SCSI BIOS as
well), but that should clear after a second reboot - without loading
setup defaults or clearing CMOS. This has to be a CMOS issue.

I find the solder points difficult to use and unreliable - a better
procedure is to disconnect the power cord, remove the battery, and short
the battery contacts with a screwdriver for 10 seconds. Check that the
BIOS clock has been reset to 1980 to verify it worked.

thanks for the responses, but meanwhile i tried all mentioned above.

- clear cmos
- load bios or setup defaults
- hitting a 100 times ctrl+a while startup with no result
- verified that it is really a p2b-s bios
- no errors were found else

but there is one thing i found out: the chip on the board labeled "aic
38600" has right after power on a very(!) high temperature... i think
the board is defective somehow 🙁

Indeed the SCSI chip burning out is among the more frequent failure
causes for the P2B-S. (You're lucky the rest of the board is still
working, this can block the whole PCI bus.) I have no idea why, maybe
the power supply design is messed up or the chips themselves are
unreliable. Hmm, the AIC3860 you say? That's the bridge chip for SE
SCSI. You /might/ be able to regain access to the LVD part by
unsoldering the Vcc leg of the IC, but that's really something for the
skilled technician.
BTW, haven't you saved the old BIOS? However, I assume that the SCSI
chip stopping working after the flash was just more or less a
coincidence, or maybe the contained SCSI BIOS is more sensitive to a
failed SE part (so that the bridge chip had been defective for a while
already which only now surfaced due to the different BIOS).
