SPARC: How to Set Up a Sun-4/1nn, 2nn, or 4nn System to Automatically Boot From the Network

1. Make sure the AutoClient system has been set up as described in "Adding AutoClient Systems" or in "Converting an Existing System to an AutoClient System".

2. Make sure the system is in the prom monitor environment.

3. (Optional) Perform the procedures in "SPARC: How to Display Existing Boot Device Values on Sun-4 Systems" if you want to record the existing boot device values.

4. At the command prompt, enter the following boot device code sequence.

   > q18 12 69 65

   This is the code for ie (the Intel Ethernet).

   What you are doing for any of the Sun-4 architectures is programming the EEPROM (or NVRAM) by entering q followed by the hexadecimal address in the EEPROM. This sets the appropriate operating system boot device.

5. Boot the system automatically from the network.

   > b

Example of Setting Up a Sun-4/1nn, 2nn, or 4nn System to Automatically Boot From the Network

> q18 12 69 65
EEPROM 018 -> 12
EEPROM 019 -> 69
EEPROM 01A -> 65

If the system output looks like the example above, you set the codes successfully. If the output looks similar to the following:

> b

EEPROM boot device... le(0,0,0)

Invalid device = `le'

you set the wrong code for the specific system architecture, and the system will not boot. You need to reset the codes. In the above example output, a Sun-4/1nn, 2nn, or 4nn was set up with the wrong device code (le instead of ie).
