Why do you think I am "possessed" with overclocking? At any rate, I believe I found the problem which makes no sense to me. In the very first BIOS screen, the "Main" area, there's the "IDE configuration" area right below the list of all drives. [Enter] on that and there's the "enhanced mode" area and below it you can select: "PATA", "SATA", or "PATA+SATA". I don't understand why, but before it was set to PATA-SATA and it worked fine, and I had to change it to "SATA" only!! Now XP tries to install as normal, and, the CDROM drive is seen by MADBOOT but for some reason it still cannot format any of the HD's. Still just flashes for an instant and does nothing. I don't get it, and I also don't get it about the PATA+SATA enhanced mode setting & why it cannot be set on an IDE HD, only the SATA.LOLROFLMAO - The something that is possessed tis you with overclocking.
Edit: Oh, and the reason I like MADBOOT is because it will format (DID format) ANY type of HD. It's a pain having to dig out the IBM, WD, Maxtor, Seagate, etc. HD installation floppies every time when a single floppy will do it. I just don't understand what's going on this time with it.
