Thanks! I'll give that a shot. (BTW for the guy who asked if I have
the special ribbon cable, yeah I do).

{rant on} Man that is really crappy that I have to do this, I paid
extra for a UDMA66 drive only to find out it doesn't work quite as
advertised. If it wasn't already several months since I bought it I'd
return it {rant off}

Now the real question is, is it worth the degredation in kernel speed
to run an i386 kernel with UDMA66 or i586 w/o it?

Thanks to everyone who has helped me!
Paul
