What model of card is it?  Not the chipset (aic7901), but the card
itself.  Most aic7xxx chipsets don't do hardware RAID.  Cards such
as the 2100S do, but that was originally made by DPT.

If the card is trying to treat it as a RAID, but the software driver
doesn't support it, it won't boot because the disk geometries aren't
similar.  Have you hit Adaptec's website to see if they have an install
floppy image for you to use during install (using "boot: linux dd")?
