Okay, this is a pretty in-depth question. So, my old quicksilver G4 (dual 1 GHz) is currently acting as my server and is running Yellow Dog Linux as its OS. Pretty good setup, however as a server, I want it to re-boot after a power failure (my UPS has been a little flakey, and has on occasion been known to give overload signals even though it is definitely not overloaded, and cut power). OSX has a setting in Energy Prefs (OS 9 had this too) where you could "reboot after power failure". This is obviously a firmware setting, and I basically want to duplicate this setting in OpenFirmware. Somehow I have a gut feeling that I'm going to have to write a firmware script or do some hex programming, but does anyone know some hidden OF variable that I'm missing?
