Help with installing 10.2 on PowerCenter |

Howdy My problem involves the Sonnet Crescendo 400Mhz G3 upgrade I recently purchased from OWC. The G3 card is recognized under OS10.1.5 without any incident on my PowerCenter 150. The machine boots into X just fine, video card syncs right up, with the L2 cache enable, the machine runs as fast as the G4 350Mhz Sawtooth I had a few years ago (which also the ATI Rage Pro 128 that I have in the PowerCenter, though of course this is PCI and not AGP). I can use ethernet to network with my G4 Dual 867, my Firewire and USB cards all work, etc. I have no problem in X with this upgrade card. HOWEVER, in OS 9, with the G3 card installed, video--either the ATI card or the internal video--will never sync up. When the Mac boots, I'll hear a chime, hard drive spin, etc, but my monitor stays black. Sonnet support says that there is a problem with video sync with some PowerComputing catalyst based motherboards. To boot into 9, I have to reintall the original processor card. Besides that, if I boot into OS9, my PRAM gets all messed up and the Mac "loses" my OSX hard drive. It takes some resetting of PRAM and CUDA to get this back. So far, I've always been able to get my hard drive back to boot into X. Once in X, it's smooth sailing. It's my understanding that to install 10.2, I have to have a G3 card installed, since it won't recognize the 604e from my original card. And, I have to install from OS9 from XPostFacto and not from within OSX. Is this absolutely true? I've got no way to boot into OS9 with my G3 upgrade to do this. Any help or workarounds would be much appreciated. I run 10.2 on my G4 and love it and would like to have the Power Tower running the same (though of course 10.1.5 is a really good OS too).

If you truly can't boot OS 9 with the G3 card (even after uninstalling all your extra cards and whatever) then you might have to manually do some of the work that XPostFacto does. Boot OS 9 with the original processor card (604e?), run XPostFacto, turn off auto-boot, set input device to keyboard, set output device to your monitor, and restart. You should end up in Open Firmware. Type shut-down or turn off the power. Install the G3 card and turn on the computer. If you can install the G3 without zapping your pram, then you should be in Open Firmware again. Type printenv to make sure the XPostFacto settings are still there (boot-device should not be /AAPL,ROM, the last line of the nvram script should be $G if hid@ ...., etc) Type boot. OS X should start booting (the gray apple will appear). If installing the G3 does zap the pram, then you have to redo everything up to getting into Open Firmware. This time, before shutting down to install the G3, you have to use printenv to get all the settings and the nvram script (It helps to have a second computer connected with a serial cable so you can copy and paste the necessary commands because the nvram script is very long). Then when you restart with the G3, hold down command-option-O-F to get into Open Firmware, and set all the settings again including the nvram script. |
