Summary: RSC - cannot access HELP!!

A huge thank you to everyone who helped, the solution to my problem was
fairly obvious and if I hadn't been in such a panic I may have thought
it out for myself.

Stop-N worked to get me my console back, however I would suggest to
anyone who is going to use E250's to ensure that the auto-boot? is set
to true BEFORE downing a system controlled via RSC. I have found the rsc
system to be very difficult to re-program once setup, the commands are
very simple but they don't work reliably even if they report success.

Many Thanks

Steve Boronski

The replies were:

I believe that if you turn the power on to any machine while holding
Stop-N on the console, this causes the PROM to reset all variables back
their default values. At the least, this should let you get in with the
console and make your settings again.

It's a shot in the dark, but you can power cycle the e250 and
hold down stop-n (l1-n for old timers) for as long as two minutes
to reset the NVRAM. This might help you. I don't have any
experience with RSC. I'm thinking of an e250 so I'm interested in
your results. If nothing else, e250s are new enough to be under
warranty support!

I believe buried in the docs you can disable by holding down control b or controll n while it boots up, and a terminal connected will take over.

try resetting nvram (note this may mess with other settings you have done in the past..)

- halt and power down the system - power up the system again - immediately after turning on the power, hold down

the "L1" key and the "n" key simultaneously. - once the banner appears, release the L1 and n keys.
