Firmware 5-37
Description
You can create an nvram script to include any commands you want the system
to execute at power-up. You create and edit the nvram script using the SRM
edit command. With edit, lines may be added, overwritten, or deleted. To clear
the script, enter line numbers without any text. This deletes the lines.
In Example 5–16 an environment variable called “mop3_boot” is created and set
to 1 on each power-up. By default, MOP boots send four MOP V4 requests be-
fore defaulting to MOP V3. This user-created environment variable forces the
SRM console to bypass MOP V4 requests. This speeds up MOP booting on net-
works with MOP V3 software.
Syntax

The editing commands are:

renumber
Renumbers the lines of the file in increments of 10.

CAUTION: Use caution when editing the nvram script. It is possible to disable
the system by including an inappropriate command. For example,
if you include the init command in the script, the system will go
into an endless loop.
To correct this error, press the Halt button or issue the RMC halt
in command, then power up or reset the system. When the P00>>>
prompt is displayed, edit the nvram script to remove the illegal
command.
