Nope, never took to GRUB.  Never bought into the selling point of "you don't
have to edit a config file for every kernel update".  Also don't have a
working sparc64 box anymore, as the Blade 100 died quite a long time ago.  I
still have a SunFire v240, but it's got a PROM release that can't netboot,
and the updated version that can was released 3 days after Oracle bought Sun
and locked SunSolve up (thanks, Oracle).  Plus the thing is as loud as a jet
engine.

As far as GRUB working on SGI systems, that's news to me.  ARCS is pretty
unique on each SGI system, so it's not like one can write a tiny bit of code
to cover them all.  I'll have to investigate GRUB's documentation to see if
can deal w/ machines running ARCS, and whether it can handle IP27, IP30, and
even IP35.
