SPARC: How to Set Up a Sun-4/3nn 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 current boot device values.

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


    > q18 12 6c 65

    This is the code for le (the Lance 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.

Example of Setting Up a Sun-4/3nn System to Automatically Boot From the Network


> q18 12 6c 65
EEPROM 018 -> 12
EEPROM 019 -> 6C
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... ie(0,0,0)

Invalid device = `ie'

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-4/3nn was set up with the wrong device code (ie instead of le).
