4-16 User’s Guide

4.4 Creating a Power-Up Script

The system comes with a special nonvolatile file named “nvram” that is stored

in 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 4-10 Editing the nvram Script

P00>>> edit nvram #Modify user power-up script, nvram

editing ‘nvram’

0 bytes read in

*10 set ewa0_protocols bootp

*list #List current file with line numbers

10 set ewa0_protocols bootp

*exit #Close file and save changes

27 bytes written out to nvram

P00>>> nvram #Execute the script.

This example shows how to modify the user-created power-up script, “nvram.” The

pound sign (#) indicates explanatory comments. In this example the script is edited

to include a command that allows you to boot the DIGITAL UNIX operating system

over the network.

Example 4-11 Clearing the nvram Script

P00>>> edit nvram

editing ‘nvram’

20 bytes read in

*10

*exit

0 bytes written out to nvram

P00>>>

To clear the script, enter line numbers without any text. This deletes the lines.
