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

1. Make sure the diskless client has been set up as described in "How to Add Support for a Diskless Client".

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).
