Disabling the SRM Power-Up Script
The system has a power-up script (file) named "nvram" that runs every time the
system powers up. If you accidentally insert a command in the script that will
cause a system problem, disable the script by using one of the methods described
previously to force a halt assertion. When the SRM console prompt is displayed,
edit the script to delete the offending command. See Section 2.4 for more
information on editing the nvram script.
