the only problem you may run into is the type of IDE controller. most modern
(UDMA133) drives i've seen can't/won't step down to udma33 (which is probably
even more modern than what you have already). the drive itself is where you
would probably run into problems. i'd say, save the headache and buy a simple
udma133 Promise card (non-raid of course) and be done with it. the BIOS will
treat it as SCSI and the controller's BIOS will boot the drive.
