... as for in os 9, I did have the lock up problem with both cpus and it was an ATi driver. I disabled those extensions and installed the drivers off of the ATi CD that came with the card and now everything runs PERFECTLY ...
I have a 500Mhz G4 ZIF in my BeigeMT system and it is stable as a rock. It is paired with a sonnet ATA/133 card and the 32MB PCI Rage Orion card ...
It was
alk's comment in another thread about Apple-included (ie, marked as part of an Apple OS in Get Info.) that set me on the path of salvation. With a Sonnet G4 ZIF and ATA-100 card, a Rev. C ROM and a Radeon 7000, either Apple's or ATi's
ATI Graphics Accelerator was a killer. There was no getting past the resulting bus error (Type 1) at the end of the splash screen as long as it was present. Ditch it. Be on your guard that ATi's software installer may reinstall it. I take with a grain of salt ATi's claim that un-needed extensions do not interfere, because it does not accord with my experience. Then replace every Apple-designated CP (one) and extension with the corresponding (and newer) ATi equivalents.
In my case, for the reason above about interference, that set of extensions reduces to
ATI Extension, ATI Guide, ATI Monitor, ATI Radeon 3D Accelerator, ATI ROM Xtender, OpenGLRendererATI and
ATI Video Accelerator. From that stable, even if limited base, it is possible to add in other extensions, one at a time, to test them.
This means that the standard installation of OS 9.2.2 will be missing
ATI 3D Accelerator, ATI MPP Manager, ATI Driver Update, ATI Rage 128 3D Accelerator and
ATI Resource Manager. Your results may vary according to your card and your need for 3D acceleration, but I have found that Apple's set, intended for a G3, does not suit an upgrade to a G4.
