Hello Mark.  The easiest way, I think, to resolve your problem, at
least, initially, is to modify your /etc/fstab so that root and swap are
explicitly mounted from /dev/wd1a and /dev/wd1b respectively.  Then, when
you have a functional system, rebuild your kernel with a new config line
which looks something like:
wd0	at atabus4 drive 0 flags 0x0000

Put it just above the wd* line in your kernel config file.

This will force the drive attached to the mother board to become wd0, and
you can then put your /etc/fstab back to using wd0.

	In addition to this change when you build your kernel, you may want to
apply the patches in kern/33445, which are fixes to the promise SATA driver
to make it more stable under load.

Good luck.
