The command in question (isp1020_edit -sd) must be issued while you are in
the SRM console, not in Digital UNIX -- the problem is that the console is
responsible for setting up the ISP1020 defaults, and may not have done it
correctly in the past. Issuing the command WHILE IN THE SRM CONSOLE will
get the defaults updated correctly on systems that support the ISP1020.
