Bug 17365

I am using a Soyo 6BA-VII+ motherboard. This motherboard has two ATA/33
ports which conform to the wdc0 and wdc1 specs. There is also a pair
of ATA/66 interfaces which the Soyo BIOS sees as a SCSI interface. When
I have the disk on the ATA/33 interface there is no problem. When I move
the disk to the ATA/66 interface, the system starts to boot, but then 
panics because it cannot find the root. I have tried various
combinations of boot [0..3]:wd([0..3],a)kernel (e.g. 2:wd(3,a)kernel) to
no avail. (BTW, Microsoft software sees it as drive C:, Mandrake Linux
sees the disk as /dev/hde [FreeBSD is at /dev/hde3]). If I attempt to
reinstall FreeBSD, it finds no disks. What incantation do you suggest?
(BTW, support for the HighPoint 66 chip has been available only as a
patch to the Linux kernel so far. It looks like Mandrake decided to go 
leading edge in their kernel.)

How-To-Repeat: Move the system disk from the Soyo's ATA/33 interface to its ATA/66
interface.
