I don't know. It should be a 93C56. I would have to open up my Indigo to check this. I know I switched these to exchange ethernet addresses between machine years ago. I wouldn't insist that the chips are socketed on all the Indigos however.

Chip ordered... and a backup just in case for the R4K that I have. Thanks!

great. Just remember that you can only reprogram the ethernet address on an R3000, but you can "upgrade" to R4000 later. The R4000 uses a different memory address for the MAC and automatically copies the MAC from the R3000 position to the new R4000 position. Downgrading (R4k -> R3k) however will void the MAC address, so you would have to reprogram in that case.

Yes understood, as I swapped boards, also it removed the password in the PROM as a simple bonus... when the R3K board went into the R4K then back into the R3K.

It's the U1 socketed chip, replaced, Plumbed in date, still won't take eaddr settings..

Then I have no immediate idea. Can you give the syntax you are using? Maybe someone else has an idea. Normally, this should work.

[indigofan]

setenv eaddr 08:00:06:12:34:56 @ the prom

[lunatic]

what about:

setenv -f eaddr 08:00:69:12:34:56

?

You usually have to use fill commands. They're gonna likely be different from the Indy version tho:

The Indy procedure is here. I don't know what they are for the Indigo.

I found this old page:
http://sgifiles.irixnet.org/sgi/indigo/hacks/

Claims you should just say: eaddr 08:00:06:12:34:56

No setenv or whatever...so try that and see?
