MVP3 or something newer?

Some early 1.7GB drives had UDMA trouble if driven by a 83mhz bus but
considering that is REALLY overclocking the drive (and chipset), it's not
really much on an issue.

FWIW, I'm running a 6.4G and a 1.7G IBM drive at 83mhz currently with no
trouble.. ;-)

VXPro, and TXPro seem to have trouble but these are bottom of the
barrel-piece-of-shit chipsets that should have never been made and prolly
don't even do PIO Mode 4 correctly. Simplex...crapex..
