I'm not completely sure, but when you would create a file boot.loader
on da0s1a containing:
  3:da(0,a)/boot/loader
the bootloader should be loaded from da3s1a.
(for more info see man 8 boot)

I worked around a similar situation by installing OS-BS (from
/tools on the release CDs) on the IDE and making the SCSI drive
the default to boot.  Not very elegant but it worked until I was
able to pawn the IDE drive off to a windows weenie. :)

How to auto-boot from an alternate disk

[Brian Somers]

Hi,

I have a machine with 3 IDE disks and 2 SCSI disks and I want to boot 
from the first SCSI disk *but* my BIOS won't boot it.

How are you supposed to do this ?

I've currently done

# boot0cfg -v -t 10 -B -s 5 ad0
# boot0cfg -v -t 1 -B -s 5 -m 0 ad1
# boot0cfg -v -t 1 -B -s 5 -m 0 ad2

Which causes things to merrily skip across my IDE disks 'till it 
finds the first SCSI disk, loads /boot/loader from there, finds my 
kernel and then drops into a dumb ``manual mount'' prompt that makes 
me say ``ufs:/dev/da0s1a''.

What I'd *REALLY* like is some way to just say ``default to 
3:da(0,a)/boot/loader''.

Any suggestions ?

Ta.
