Sun Box will not auto boot

[Tim Fadden]

Oops I was thinking you were running Solaris. the eeprom command is 
for solaris.

The boot-device must be set for the scsi target of the disk you are 
booting from.

on a sparc 5 disk=target3, disk1=target 1, disk2=target2, and
disk3=target0

The default is to try to boot off of the first partition (0) 
as in sd@3,0  target3, partition0

Not sure about linux, but for solaris, the boot loader is on the first 
sector of the disk, and points to the vmunix file on the boot partion.

from the OK prompt type

ok probe-scsi this will print out the scsi devices on the internal 
scsi controller.  I think linux sets the lowest scsi id to a, and the 
next higher b, etc etc....

if you have multiple scsi controllers on the system, use

ok probe-scsi-all

I'm a system service engineer for Sun, so know solaris and sun hardware.
I have never loaded linux un a sparc5, so not exactly shure how the boot
strap gets started... lilo I assume..   any way find the scsi id of the
"a" disk and set the boot-device to that one.  My guess is that sdb is
target 3, which the variable disk points to... therefore the illegal
instruction.
