SCSI Disk not found

What do you mean SCSI HD show in PC bios?  I have not seen any PC
bio's that know about SCSI drives. They are not part of the normal
PC hardware inventory. SCSI drives are 3rd party hardware. Your
bio's option 'drive to boot from' is the only place that knows about
SCSI. It should say boot from SCSI drive, or something along those
lines. The SCSI PCI control card knows about the 2 drive if it's
there. During the PC boot process you should see msg about SCSI
controller being enabled. AT that point you should be able to enter
SCSI setup utility.

I see from dmesg that both drives are using same irq. This is common
problem with older PC bios, FBSD can not reassign different IRQ to
second device.   Add  device puc statement to your kernel source and
recompile kernel. Them check Dmesg boot log to see if different
IRQ's get assigned.

Before you installed FBSD on this PC, was it running ms/windows and
did you see the both SCSI drives?

I wish it were that easy... I really meant that FreeBSD does NOT
see it at all. I have tried to mount it myself, but it tells
me that the device is not configured.

The SCSI hard drive appears in the system BIOS, and when the machine
first boots up, but it is gone everywhere else.

Any ideas?
