Creating A Power-Up Script - Compaq AlphaServer 1200 User Manual

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
editing 'nvram'
0 bytes read in
*10 set ewa0_protocols bootp
*list
10 set ewa0_protocols bootp
*exit
27 bytes written out to nvram
P00>>> nvram
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.
