SPARC

The HW-Commands:

boot

boot -a

Boot in single user mode:

boot -s (e.g. boot cdrom -s)

Then you probably want to mount the drive:

# fsck /dev/rdsk/c0t3d0s0
# mount /dev/dsk/c0t3d0s0 /a

For problems in the boot process this is a very good ressource.

To start my Ultra 1 from CDROM (which was set to SCSI ID 1:0 instead of 1:6, I had to:

boot /sbus@1f,0/fas@e,8800000/sd@1,0:f

probe

A very handy command:

probe-scsi-all

NVRAM

I got an Ultra 1 that complained about an invalid Checksum and stuff. It reported FF:FF:FF:FF:FF:FF as MAC address also. I found out that I had to get a new NVRAM, which I ordered online. Then I had to reprogram the thing:

01 0 mkp
80 1 mkp
8 2 mkp
0 3 mkp
20 4 mkp
ab 5 mkp
ab 6 mkp
ab 7 mkp
11 c mkp
11 d mkp
11 e mkp
0 f 0 do i idprom@ xor loop f mkp

This sets all the memory locations with the MAC address and HostID. http://www.squirrel.com/sun-nvram-hostid.faq.html#SYSTBL is the reference I used to reprogram this thing.
