I have a Dual PowerMac G5 (PowerMac7,2), PPC970 revision 2.2 (pvr 0039 0202). I have both MacOSX and Linux installed. After clearing the boot-device variable in NVRAM, the machine booted normally (into MacOSX). I suppose it would be better if someone did the test on a system where *only* Linux is installed, to make sure that OpenFirmware is able to find GRUB without boot-device being set. John Ogness
