Booting in Single user Mode when auto-boot=true

Making a short story long...

My /etc/password file has a bad shell for root (/sbin/ksh rather then /usr/bin/ksh).

I have found no way to signon without it dropping me out because of the bad shell.

Tek-Tips recommends that I boot in single user mode.

My problem here is that the eeprom has auto-boot?=true. Since I do not have root access, I can not change this to false.

Is there any way to go to the OK prompt so I can boot off the CD and into single user mode with auto-boot set to true?

Digging a Hole deeper and deeper for myself....

Thnanks....
 
I'm sorry,

What is Stop-A?

There is no console, we hyperterm into it.
 
Stop-A would be the way to break to the OK prompt in a 'normal' setup. Alternatively, try:

Ctrl + esc + a

ctrl + esc + b

shift + esc + a

shift + esc + b

One of these might work for you.
 
If you still can't get in, try to take out the boot disk and it'll force the system go to OK prompt. Once you change auto-boot to false, then you can do whatever you want... ;-)

Cheers,
 
There is always the old method of shoving a keyboard in the back and then removing. Repeat several times and it should take you to OK>
 
Apologies, I mean plug of course! On older systems an individual keyboard used to plug into the back of a Solaris box. In recent times setting up an async 9600 connection into the serial port and then unplugging can also halt a system.
 
If the serial port is defined as the console and you hypertemr into it.. you can:
A) have hyperterm send a break signal, this will drop you to the OK prompt unless the key is in the locked on position of any Sun box.
B) disconnect the serial cable and reconnect it, same warning about the key.
C) use something (i.e. ANYTHING other than hyperterm) and send a break signal to the serial console.
If none of these work, make sure the system key is not turned to the 'locked' position.
