A possible fix for a highly unstable G3 or G4 Tower
Authored by: xSmurf on Sep 07, '05 12:51:30PM

I have experience similar errors while installing NetBSD on a 6500 (OpenFirmware 1.0.5). As explained earlier it happens when the firmware can't load the bootloader. This could be because it the drive hasn't started yet, the floppy is messed up, etc. One thing you have to remember is that OldWorld machine don't have much support for the Open Firmware (it was never inteded to do anything else than boot MacOS, if it did that, there was no need to debug any further). It can also occure if the real-base and load-base variable aren't set properly. This said, the default cache error can also occure "randomly". Indeed, on the 6500 if I tried the command that gave the error a few times it would eventually boot. The NetBSD documentation has some good information about this common problem. I would strongly suggest that you give it a look @ http://netbsd.org/Ports/macppc/faq.html#default-catch

May I also add that from what I've heard xPostFacto will not work on every machine. Or at least OS X won't. I have a friend who was trying to get it to run on a 7500 with a CPU upgrade to no avail (OF & Kernel errors). He even tried a different board and tried swaping most components. No go. He ended up buying a 9500 motherboard. So beware, even if xPostFacto allows you to install OS X, it doesn't mean it's gonna run properly.
