                           Boot Prom Version

1.  Copy sx00103.a10 to /  (Root Directory)

This update must be performed from the boot prompt. Shut down your system to 
get to the boot prompt.

2.  shutdown -h now    

At the `ok'prompt,

3.  cd /sbus

4.  ls

The output will be similar to the following:

     "ffeada28 ia@1,0"
     "ffeac140 le@0,c00000"
     "ffea8c2c esp@0,800000"
     "ffea8be8 dma@0,400000"
     "ok"

In this example the ATM adaper (ia) is located in sbus slot 1. You will need
the slot number for step #9. Replace <slot#> with 1 in this example.

     "ffeada28 ia@1,0"	<------ ia "at" SBus slot 1
                  ^
                  |____ SBus Slot #

5.  setenv auto-boot? false
6.  setenv fcode-debug? true
7.  reset

When you return to the `ok',

8.  boot sx00103.a10 -h

The system will load the file and halt at the "ok" prompt.

When you return to the `ok',
