hi there
I have removed the NVRAM chip from my Ultra 60 and managed the surgery required to get a lithium battery piggybacked on to it.
It seems to have worked, and now I can reboot the machine and it
remembers the date and time. Solaris 10 gets up and runs but as you can probably guess, the MAC address is completely blank, and I cannot get
the network to run at all.
Does anybody know of an idiots guide to the business of reprogramming
the chip with some sort of (presumably dummy) MAC address ?
Also, I am assuming that the on-board ethernet port has its MAC address
held on the NVRAM, which explains the current situation, but ....
I have a couple of Sun SCSI adapter cards which have ethernet ports on
them, and I have used these ethernet ports in the Ultra 60 before - but
now if I insert one of them, the card is recognised, but the MAC address
for it is also blank - so where is the MAC address for the card stored ?

I left this one alone for a long time, mainly because I managed to get
the thing working in a fashion.
The NVRAM seems to keep hold of the date and time but not a lot more, so
I just fired it up and used ifconfig to feed it an ethernet address and
the other network details, and left it running. It seems happy enough
for weeks on end.
When I did get some time to look in to it a bit further I managed to
enter the programming mode, but any time I tried to enter some data,
there was an error message saying "Fast Data Access MMU miss" or
something of the sort - any suggestions ?

Sun machines of that vintage have a single mac address, irrespective
og the number of hardware interfaces. Quite easy to program that
into the machine using obp. Don't have a link, but search for
sun nvram faq, which has all the gory details...
