I am in the process of cannibalizing a Dell Precision 220 and I've run into something that has me stumped. It as two hard drives a 10 GB (logical drive C) and a 250 Gb drive (logical drive E). I have removed the partitions from the 10 Gb drive and erased it. The OS (XP) is on the E drive which is installed as IDE1 and configured to master while the C drive is IDE2, set as slave. When I try to boot the system without the empty drive I get kicked into the BIOS setup which shows no drives at all, including the CD ROM. Since I'm taking it apart you might wonder why I even care. True, I don't really need to know this, but I'd like to understand what is going on.
