Getting to the PROM Prompt

On a Sun server, you can get to the boot-prom by:

- holding down the STOP and A keys (modern Sun keyboard),

- holding down L1 and A (old Sun keyboard)

- pressing Ctrl-Break (dumb terminal)

You can also get there by unplugging the console and plugging it back in. Instead of seeing a 'login' prompt, the will see either:


or on a really old system:


In both cases, if you didn't mean to get into this state, type 'go' and the system will resume where it left off (it was just sort of suspended). Note that if you leave it suspended for too long some processes will die on startup (because their connections or wait requests have expired).
