Changes to PC Bios before installing FBSD

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.

Virus Warning=, set this option to disable. It's a firmware check of
the hard drive boot sector looking for MS/Windows boot virus. This
will stop FBSD booting from the install CDROM.
set to disable

plug-n-play=,  set this option to disable. FBSD is not sensitive to
Microsoft plug-n-play standard and may refuse to install, or cause
PCI cards not to be found.
not available on BIOS

Disable or set to auto any Bio's option to assign irq numbers to PCI
expansion slots.
 

all set to auto

Disable any ISA expansion slots.

Operating system type=, set to 'other' or any Unix type of operating
system, don't set to MS/Windows.

Check to see if the cdrom drive is the slave to the IDE master Hard
drive you are installing to, if so then move the cdrom drive to the
secondary IDE controller as master. There should not be any cdrom
drive sharing the primary IDE controller with the master Hard Drive.
 

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.

boot sequence=, set this option to (CDROM,C) Since you are
installing FBSD from CDROM you must tell the PC what I/O device to
look at to boot from. Keep in mind that some older CD-ROMs drives
and older PC bios do not support booting off CD-ROM. Generally with
PC manufactured after 1999 this is not the problem.
 

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,

original request:

I have IBM 325 PCServer with one 200 Pentium Pro CPU and two SCSI
HDD
drives and a SCSI CDROM.  I'm installing FreeBSD 4.9 via floppy and
it
hangs when it says:
Waiting 15 seconds for drives to settle

I notice that it is accessing the cdrom, during the wait, but
nothing
else happens.  I've checked the mailing list and all I see is to
turn
the bios virus detect off.  It seem that quite a few people are
having
this problem...
any ideas? interrupt problem?
