If I were you, I wouldn't be concerned about UltraDMA; FreeBSD doesn't support it and it will be disabled anyway. > The kernel appropriately finds the drives as wd0 and wd2, but panics when > it can't mount root on wd0 (as it should).

If you get the message: panic: Cannot mount root At the end of the probe sequence you should either: 1. Have the line: config kernel root on wd2 in your kernel config, OR: 2. Rename the second disk to wd1 in the kernel config (comment out the original wd1 line and change the wd2 line to read wd1, leaving all other parameters unchanged). > PS- Where are the docs for the "Boot:" options?
