I think you have to boot it from CD, unless it's enough like a Challenge
L/XL to use POD and the "zap" command.  Google "origin NVRAM password" and
"origin PROM password" for some ideas.

I doubt 6.2 supports the Origin architecture, and, even if it does, the
appropriate files probably wouldn't have been installed on the Indy.

You can probably pick up a non-current version of IRIX off eBAY for cheap,
enough to get the machine running.  Once it's running, you can update it,
patch, etc., with the files on SGI's website.

What part of the country are you in?  Perhaps someone close by can lend you
some disks.
