        Unfortuantely, no... I did have IRIX on the HDD when I first got the
box last year, that was the first thing to go when I installed Linux.  I
managed to download IRIX 6.5.30 off SGI's website, but I still lack the
foundation CD packages.

        I've figured out how to netboot IRIX off a Linux server (just grab sw
and miniroot/unix.IP32 off the first overlay CD and stuff them on a
convenient TFTP server) and even install things.  However, I get loads
of conflicts in the "inst" utility, and the end result is a system
lacking just about every core component of IRIX.

        I'd be nice if SGI just released a bare-iron IRIX install that *just*
had flashinst for this purpose... but fat chance of that happening.
(Heck, even releasing tarballs of the Foundation CDs would be nice...
hint hint SGI?)

        I've looked around on NekoChan's forums (as suggested by Regan Russel
privately), most of the people there installed IRIX 6.5 straight away,
and thus probably never will face this issue since their PROMs will be
updated automatically during this installation process.  For the purpose
of the archives (and anyone else who may strike this issue), the message
I get is this when the RM5200 CPU is installed:
