Dear Sun Managers,

I've an E3500 with Solaris 7 (KJP 106541-16 ). After
the replacment of the CPU/Memory Board 5 due to some
h/w problem, the PROMs version for the boards
are different.

The prtdiag outptut showing me board 5 and 9 are
having different OBP version.

System Board PROM revisions:
----------------------------
Board 1: FCODE 1.8.28 2000/12/20 12:22 iPOST
3.4.28 2000/12/20 12:28
Board 5: OBP 3.2.29 2001/06/18 17:28 POST
3.9.29 2001/06/18 17:50
Board 9: OBP 3.2.28 2000/12/20 12:24 POST
3.9.28 2000/12/20 12:29

At ok prompt, when I try to run "update-proms" as told
by the bootup messages, I'm getting MMU miss.

ok>update-proms
copying FPROM from board 5 to 9
Fast Data Access MMU miss

When I try to boot up to OS, prtdiag still shows me
Board 5 and Board 9 are different
version.

My questions are:

(1) What does MMU miss during update-proms command was
issued?
(2) How to update the PROM level to be the same?

TIA.

Regards,
Tim
