When booting from the MOS 3.0 CD-ROM, it works until it tries to bring up the Ambient desktop. It's apparently trying to use a 50 Hz screen or some other resolution that my 60 Hz monitor can't handle. I've tried two different monitors but same story. I remember holding down a key when I installed 2.7 which forced it into standard VGA resolution but I can't remember the key. Could somebody remind me what that key is? I'm on a PowerMac 3,1 G4 500 MHz with a Radeon 9x00 PCI series Mac version.
