Power down the machine to the firmware ok prompt. You should be able to 
do that with :

    shutdown -Hh 'now'

The capital " H " should just halt the linux os and leave you as the prompt.

Then do this :

    setenv diag-switch? true
    setenv auto-boot? false
    setenv verbosity max

Then do printenv and check if the diagnostics verbosity is actually set 
to maximum. On the old Ultra 30 it may be named something else.

Then issue the golden "power-off". Unplug it from the AC power.

Go get a coffee.

Then power on the unit and watch all the diagnostics happen.

I do not recall the specifics of the Ultra 30 but if you issue this to 
the forth ok prompt :

    sifting post

You will get a list of commands related to POST status. One of tham may 
actually be post-results or post-status. Issue that command.

If the result looks sane then "setenv diag-switch? false" and boot the
system as per normal.


Just my thoughts from the distant memories.
