booting external scsi disk on my sparc lx (fwd)

[<dfinn@faderautomatic.com>]

I've checked online and haven't been able to find much about this.  I'm
having trouble booting off of an external scsi disk attached to my sparc
lx.  Here's the brief story: I got my lx with one 2 gig internal drive.
That drive acts up at times and spits out IO errors, essentially I think
there are just bad spots on the drive and it's old.  I was given an
external 4 gig drive.  I formatted the external drive, cpio'ed everything
off of the internal drive over to it and it works fine.  I'm running off
of it now.  The only way I've found that works to boot off of it is to do
boot -a and then provide this as the boot device:
/iommu@0,10000000/sbus@0,10001000/espdma@4,8400000/esp@4,8800000/sd@5,0:a

This works fine.  I'd like to just boot normally from the boot PROM but I
can't get that working.  I've made a device alias to that and tried it
different ways but I can't get anything working.

This is what happens:

Rebooting with command:
/iommu@0,10000000/sbus@0,10001000/espdma@4,8400000/esp@4,8800000/sd@5,0
Boot device:
/iommu@0,10000000/sbus@0,10001000/espdma@4,8400000/esp@4,8800000/sd@5,0
File and args: bsd
Instruction Access Exception
Type  help  for more information

I've looked through the disklabel man page and I think I've installed the
bootstrap correctly.

Any help would be really appreciated.
Thanks
