Thanks, but that is the problem. When I go into the BIOS, the only choices are booting from the floppy, CDRW, my new IDE hard drive, or from a LAN appliance. There is no other option. I notice on a different computer I have with a Asus P4P800 mobo, there is a raid array boot option. I have no idea why there isn't one on this mobo (P4B533E) and I was hoping someone with the same mobo could tell me where in the BIOS can I set this, or how can I add a new hard drive on either the IDE PRI or SEC channels.
