I asked about repairing a 386i/RR250 which was showing
symptoms of Ethernet hardware failure.
Thanks for the quick responses:

- has a spare part contract through DEC, so doesn't have to worry
about these things :)

- blown fuse - good guess, I had checked already.
and the winner:
email@example.com (Kevin Drysdale):
I recently experienced a problem with a 386i/250 myself. Although it
wasn't directly related to the ethernet, the solution I found can be
related to many different failures. I learned from Sun that the NVRAM
in the 386i is VERY unstable. It has a tendancy to loose some of it's
values for no reason at all. In our case the NVRAM was loosing data
because of a weak/dead battery which is built in. Replacing the NVRAM
fixed the problem.
I followed Kevin's suggestions on checking two NVRAM locations, one of them
was flaky, that is it changed during the boot process. I wrote the correct
to the location prior to booting, and everything seems OK now. Kevin got
his new NVRAM through his service contract with Polaris Service, and
suggested I try Apex (1-800-654-8222).
Does anyone have an alternate sorce for this part, or at least a field
engineer handbook so I can identify it?
