Just a note to remind everyone that you can change your fstab to use DUIDs rather than wd* and sd*, thus making it easier to survive the flips between wd and sd when changing BIOS settings. Using wd0 as an example, just 'disklabel -E wd0' and w(rite), q(uit) to put a DUID in your disklabel if it hasn't got one. Then replace all instances of '/dev/wd0x' with <duid>.x in your fstab. And away you go. No need to worry about your disk flipping from wd to sd and back. Just did this and it works fine. My fstab now looks like d48d0e3fc1c39531.a / ffs rw,softdep 1 1 d48d0e3fc1c39531.k /home ffs rw,nodev,nosuid,softdep 1 2 d48d0e3fc1c39531.d /tmp ffs rw,nodev,nosuid,softdep 1 2 d48d0e3fc1c39531.f /usr ffs rw,nodev,softdep 1 2 d48d0e3fc1c39531.g /usr/X11R6 ffs rw,nodev,softdep 1 2 d48d0e3fc1c39531.h /usr/local ffs rw,nodev,softdep 1 2 d48d0e3fc1c39531.j /usr/obj ffs rw,nodev,nosuid,softdep 1 2 d48d0e3fc1c39531.i /usr/src ffs rw,nodev,nosuid,softdep 1 2 and changing my bios setting to flip back and forth from wd0 to sd0 has no effect on booting. ....
