I just upgraded an SS1000 from PROM 2.25 to
PROM 2.31, and thought I would share a secret.
It seems that Sun has been replacing motherboards
every time the PROM upgrade fails, which is often.
*** It may not be necessay ****
The system is a Sparc 1000 with Solaris 2.5.1.
When we turned on the system, it ran and passed
the Power On Self Test. Then,
it got an error trying to boot.
We got an <ok> prompt.
probe-scsi-all reported the correct numbers
(I had noted how many drives per controller).
We checked everything and the Field Engineer
prepared to replace both motherboards per Sun
procedure. Before changing them, though,
he called the FE's support line.
A Sun engineer advised him that a parameter
in the system, "use-nvramrc?" is set to TRUE.
When we changed it to FALSE
<ok> set use-nvramrc false
This value must also be saved. I can't remember
the exact command. Use help to find it.
Then
<ok> reset
The system came up fine.
