Thrift store find

well i really couldn't figure out where to put this thread, but any ways i recently went to the thrift store and found a clean tyan s2925 mother board biased server and figured id get it fix it and might make a quick buck off of it, or use it. but now when im trying to install debian, the drive isnt being recognized by the bios. hdds are functional and debian see the drives and the nvidia nforce 3400 raid controller sees them too. the bios at one point saw them but not any more. ive tried /g/ on 4chan and searched a fix for this but i cant find anything

Check to see if you have the latest bios.
