Hello everyone, I'm new on the forum. I have a problem with a G4 PPC Powermac that I can't figure out. Whatever i do, I'm unable to boot into open firmware. Not only that, but I can't boot from a CD holding the C key or go into "choose your booting" mode with the Alt key. I can't go into target firewire mode either. I've tried with another keyboard, I've tried disconnecting one of my HDs (I have two), I've tried with and without a mouse and with every USB port, but nothing will do. Whatever I try, the Mac just boots form the HD (and takes forever, too). This Mac is second hand: maybe the first owner did something weird to it? I have an old iMac and it will boot into open firmware with no problem. Any ideas?
