	In order to run full UDMA66, you need the 80 conductor cable and a proper
controller.

	The cable should be easy to come by.  The controller, on the other hand, is
going to require an additional piece of hardware.  Since your motherboard is
one of the "lower end" (trying to put it as P.C. as possible), I would doubt
that it would handle Ultra 66 on the board, even if that was an option.  You
would want to look at adding a Promise Ultra 66 (I have one, and it's been
flawless) or similar card to control the 30 Gig drive.
