Yep those pre Y2K boxes are an real pain in the ass when it comes to
their bios.

it's time to replace your bio's
chip with an modern one.

Check out www.unicore.com   800-800-2467 for new bio chip.
They will give you instruction on how to get the technical info on
your bio chip,
so they can price the replacement.
I have replaced 3 over the past 4 years and each time it cost me
$70.00 each.
This is the only way to extend the life of old PC's.

Good luck

unfortunately, the BIOS on the machine is from 1997.  It's IBM's
SureBIOS.  I've tried finding a update on IBM's site but no luck.

The HDDs and CDROM are on SCSI, so I don't think they have any IDE
controller.  Anyone can feel free to correct me on this issue if I
am
incorrect.

BIOS is old so the old boot option I have is floppy.  The SCSI BIOS
had
a boot option, which I tried.  That failed however, and brought
error
codes from the PC BIOS because it moved the floppy drive to B: and
took
over the a: slot.

When FreeBSD attempts to boot the machine, ahc0 driver (for the
Adaptec
AIC-7880 controller) is loaded but throws the weirdest error:
ahc0: Illegal Configuration. Only two connectors on the adapter can
be
used at one time.
which means nothing to me.  Does anyone know what it is asking for?
I
even tried removing the CDROM from the SCSI and booting , but the
same
error appears.

Others have loaded 4.9 on 325 PC Servers, however there is something
about my configuration that is giving the ahc0 driver fits.

again, please cc with your response as I am not on the list.

Thanks,
Andy Clements
