I just bought a new hard drive(100gb)for my older puter(pentium2) and cant get it to recognize it.........i am not a computer wiz but have been told i need to upgrade my bios............this puter was hand built and does not have a brand name...........where on the motherboard or where can i find the info needed to to find out brand where i can look up the up grade on net? This hard drive will work on this puter i hope. Thanks for any info.
