These things are so flaky to install OS X on (for very many of us), I can understand why - despite understandable protest - Apple were reluctant to offer OS X support for these old-world machines.
I was doubtful, but one of the few people who bothered to try to help me with this suggested I just install Jaguar on my B&W and then boot the beige from it. But sure enough, I start with the "X" key pressed and it blips an OS 9 screen, chimes, and boots the Jaguar screen! Finally!
The problem now is that the Jaguar boot screen appears on the built-in video out, not my Rage128 card. And then, as soon as the gray boot screen finishes, as the login window is supposed to start, the monitor goes black! The OS does keep loading though.
I have no idea how to configure Jaguar to use the Rage128 video. OpenFirmware defaults to the card, but Jaguar doesn't. I can boot from the OS 9 CD, so if I knew that I could edit a file or move some things around, it might be possible. I took the "RagePro.kext" out of the extensions, hoping that with no driver it'd boot with the Rage128, but no such luck. I wish I could remotely log in to this machine and fix it.
At least it runs better than it did yesterday!
