Anyone in the computer parts refurbishing business ? [SUN Hardware]

(1/3) > >>

resistance:
I would very much appreciate any help on refurbishing a SUN 25K CPU board (part number 540-6834-02).
Any schematics, procedures will be invaluable.

The board is already refurbished (alas unsuccessfully. == DOA) and gives out the following error on post:

FAIL Proc SB4/P0: Serial number of CPU (########.########) doesn't match data in board SEEPROM (########.########)
(Serial numbers omitted on purpose)

Thanks in advance.

Whales:
I don't have schematics, but I assume the eeprom chip will be something obvious and separate.  If so, you could try removing it (or accessing it in-circuit) and searching for the ID string + replacing it.

Good luck :)

resistance:
Hello Whales, and thank you for taking the time to answer.

You are correct, and this is my last resort.
However, I strongly believe that refurbishers (!?) follow a more higher level technique.
Like plugging the board  somewhere and running some little application...

Anyway thanks mate.

Cheers

Whales:
That would be more advisable, as more than just the serial may be off. 

Are you refurbishing for personal pleasure, or is it needed for operation?

n45048:
I may be able to find you a replacement board if that helps? I'm not familiar with SUN gear myself but know someone who might have parts stashed away. Can you upload photos?
