Yes, check the bios and if it does not show up there and you know that the 
disk is fine, try to find the kernel switch with which you tell the kernel 
not to listen to closely to what the bios say and rather do its own thing.
I have used that in the past to make linux see bigger drives than what the 
bios saw.
I forgot the kernel paramater, but it was something like pcibios=no.
Also have a good look at the output of dmesg and /var/log/messages to see 
if the disk is seen anywhare.
