First, make sure you are using FreeBSD 5.4.  Second, try updating your BIOS on 
the motherboard and on your SCSI card, often this may help.

You may have to adjust some BIOS settings, so experiment.  In particular, what 
you want is for the BIOS to recognize your devices and assign them as drive C: 
(0x80), D: (0x81), etc.  If this doesn't happen, your MB may simply not deal 
with both SCSI and IDE being present at the same time.  If so, try doing the 
install with just the IDE drive present.

For more help, it would be useful to know what your SCSI controller is and 
whether it is supported.  Check the FreeBSD release notes.
