Stuck on OBP Ok Prompt. Doesn't take any input except STOP-A
Posted on 2006-05-02
I am stuck on Ok Prompt of a Sun Ultra 2.
No Sun Monitor.
As I boot the machine, I can do STOP-A from serial port connection and get to OK Prompt.
Then am no able to give any other input like printenv, setenv or boot.
I have a Sun keyborad as well but that doesn't provide any input while connected.
Even I disconnected the keyboard, I couldn't make Ok prompt to accept input.
Without Sun monitor, just using a guess:-
I tried by disconnecting serial connection , booting and pressing STOP-N to reset to defaults.
Also tried by disconncting serial connection and trying STOP-A and then typing "setenv input-device ttya".
When I connect and check from serial connection, still the same thing. STOP-A works but no further input accepted.
I have done it a lot of time but this time every combination of possibilities failing.
Pls advise, is there anything like reseting some jumpers to get the defaults.
