Creating a Power-Up Script
The system comes with a special nonvolatile file named “nvram” that is stored in
electrically erasable read-only memory (EEROM). Nvram is a user-created power-up
script (set of commands) that is always invoked during the power-up sequence. Use
the SRM edit command to create or alter the nvram script.
Example 5–16 Editing the Nvram Script
>>> edit nvram
editing ‘nvram’
0 bytes read in
*10 set ewa0_protocols bootp
*list
10 set ewa0_protocols bootp
*exit
27 bytes written out to nvram
This example shows how to modify the user-created power-up script, “nvram.” In this
example, the script is edited to include a command that allows you to boot the
Tru64 UNIX
operating system over the network. See the following page for a list of editing commands.
Example 5–17 Clearing the Nvram Script
>>> edit nvram
editing ‘nvram’
20 bytes read in
*10
*exit
0 bytes written out to nvram
>>>
To clear the script, enter line numbers without any text. This deletes the lines.
