SGI O2s... that brings back some memories.  About 2 years ago I worked
on creating a cluster of O2s and Indy workstations back at the college I
graduated from.  I used a version of Debian.  The SGI Machines use
different versions of the Rxxxx processors... which have similar, but
not exact architectures.  My Indy kernels would not boot the O2s.  These
machines however, have the ability built right in to tftpboot.  What was
arcane was figuring out the settings required for the SGI "BIOS" in
order to network boot.

Try this link... it looks familiar (there are some special tweaks to MTU
or something, otherwise TFTPBOOTs might fail or timeout):

I've never compiled a version of LTSP (or at all), for a different
architecture, so I don't know the requirements. I've played with cross
architecture compilers, but it has been awhile.

I got this link from the linux-mips wiki:
He appears to have some working kernel versions..., so all you would
have to do is get a network booting version of LTSP for MIPS going...


What I ended up doing with the SGI Indy workstations was configuring
Debian on a drive, and copying the files to new drives for the new
stations.  The O2s would make it easy since the SCSI drives pop in and
out the back in their nice SCA connectors..mmmm....  Oh, putting the
kernel on the drive takes some magic too....

Check this link out for help

Hopefully my rambling makes some sense.  Good luck!
