[rescue] Challenge L Rescue

[Sheldon T. Hall]

OK, the Tandem-badged Challenge L is in the house.  It runs, it boots, etc.

Its a four-R4.4k processor IP19 with 1.5 GB of main memory:

----------------------

All sleds are present and accounted for: 3 x 2-GB hard drives, a CD-ROM
drive, a 150 MB tape drive, and some myster drive that looks like a tape.  I
disconnected the tape drives for the above hinv report, as the start-up
procedure was hanging with a "checking inventory" message on the LCP panel.

And my question is ... what's the best way to crack root on this thing?  I
have a set of IRIX 6.5 media...
