[SunHELP] root unknown & STOP-A disabled

[Peter Stokes]

Hi Kurt

In case you are still having problems. I agree the only way is to uncable
the hard disk and this should result in the ok prompt. When there set the
auto-boot? variable to false and then switch off and reconnect the disk.
Then switch on and you should be back to the ok prompt.

Peter

Crazy suggestion here - but I've been on a roll today in the "wild guess"
department.  What if you detach the hard drive?  Logic says (to me, in my
wacky state of mind today) that it won't be able to boot, and will error out
to the OK prompt.

>From there you should be able to enable STOP-A, reconnect the hard drive,
boot from CD, and so on...
