MkLinux on g3-upgraded 6100
It works for the Newer cards (I have one), but not the Sonnet cards.
For the Newer cards, you just have to play around a little bit with the
extension loading order.
There has been talk of attempting to get the Sonnet cards working, now
that MkLinux can be started off of BootX instead of the MkLinux Booter,
but I don't think that's gone anywhere yet.
Let me know if you want any more details about getting it running on
one of the Newer cards.
