i will do that.

i have it fixed to compile now ;-)  we will see if my other changes
work shortly...

i changed around the tests some.. i think this needs to be done
differently anyway.

i think so, thats what im using now.

i mean some machines to boot quik only need boot-device changed from
/AAPL,ROM (MacOS) to whatever the OF device name is to the disk.  but
many machines seem to fail to boot with this, beige g3s in
particular.  g3s can't even read from the disk at all without apples
patches.

hmm, setting output-device and input-device could be useful, but only
on machines that it will work on.  for say a 7200 its useless since
they have aboslutely no ability to display to the monitor at all.
changing these variables would in fact be harmful in those cases as it
disables the dumb terminal attached to the serial port.  (every
oldworld owner should have a dumb terminal)

even the beige g3 lacks a screen alias unless you install apple's OF
patches.. (at least some of them are that way).  

so overall i think this is probably not a good idea, at least right
now.

i may commit the confirmation dialog change tonite. you already have a
dialog there, it just needs to be reworded.
