Hi all, I have an Inspiron 530 with the latest BIOS.  I took the hard drive out of my old computer (had previously given me the blue screen of death) and put it in as a 2nd drive in this 530.  I have vista on the 530 and had xp on the old on.  I have the disc and want to reinstall xp on the old on.  How do I go into BIOS and disable the vista hard drive so I don't mistakenly reinstall xp on the wrong drive?  I previously tried this with only moving the vista drive down and putting the xp drive as the first drive (after the cdrom) but somehow ended up overwriting my vista and had to completely reinstall vista (thank God for backups).  I don't want to make that mistake again, how do I disable the vista drive so it doesn't know it's there until I'm done instally xp on the old drive?  Thanks!
