Description
This document describes how to use Open Boot Prom menu to trouble-shoot
a Sun Blade[TM] 150 from the OBP level.

Steps to Follow
To get to the menu level do the following steps:

1. Power up the system
2. Hold the "Stop" button and hit the "A" key (after system displays
banner)
3. Change the following environment variables at "ok" prompt
	a. setenv diag-switch? true
	b. setenv diag-level menus
	c. setenv auto-boot? false
4. Reset the system by typing "reset-all" and hit the "Return" key
System will reset, goes through extended self test and will display the
menu options as following:
0       Run POST
1       Demon Level 2
2       Initiate Soft Reset
3       RIO Basic Menus
4       CPU Basic Menus
5       FPU Basic Menus
6       MMU Basic Menus
7       Cache Basic Menus
8       Ecache Basic Menus
9       Processor Basic Menus
a       SC Basic Menus
b       NVRAM Basic Menus
q       Return to OBP
Each one of the above options can be selected by entering the corresponding
number/character next to it.
For example, if we choose to run "Processor Basic Menus" tests, we do the
following:
0       Run POST
1       Demon Level 2
