I asked:

>(slice..) resides, by booting from CDROM and mounting /dev/dsk/c0t0d0s0,
>which works fine.
>So what's going on? I had this machine working with 2.5 on it a while

for replying.

The problem was I had forgotten that /dev/dsk/c0t0d0s0 corresponds to
sd(0,3,0), not sd(0,0,0), because of a curious remapping of the target ids
(anyone have any idea why Sun did this?). Anyhow, my machine boots fine
from sd(0,3,0)...
