Tom -- I think Harry's main problem is the BIOS does not want to
recognize the drive and takes a long time to timeout on boot. Once
things get to the kernel, all is OK. Also, I don't think Harry seems
to care whether the drive functions as UDMA33 or 66. 

Since I've run out of other suggestions, I can only now suggest to
Harry that he not reboot ;)

FWIW, I have a WD 13G UDMA66 on a BP6 with the std controller, and
never had any problems at all -- either BIOS or Linux. Running UDMA33,
but I don't really care.
