Editing the Nvram Script
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.
The syntax is:
edit file
file is the name of the file to be edited.
The editing commands are:
help Displays the brief help file.
Lists the current file prefixed with line numbers.
list
Renumbers the lines of the file in increments of 10.
renumber
Leaves the editor and closes the file, saving all changes.
exit
Leaves the editor and closes the file without saving changes.
quit
nn Deletes line number nn.
nn text Adds or overwrites line number nn with text.
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
command, then power up or reset the system. When the P00>>>
prompt is displayed, edit the nvram script to remove the illegal
command.
