Hi everybody!
I have PowerMac G4 MDD (FW400, 2003), I can't boot into Mac OS 9.2.2. For 1 month I've been trying to launch Mac OS, discussing my numerous attempts in the topic of
forum.
Sometimes the OS boots with errors or failures, but in most cases I only get a gray screen.
There is a suspicion that this MDD has incompatible or faulty equipment.
The last time I started booting Mac OS 9, I did it several times in OpenFirmware:
dev /
13fff encode-int " AAPL,debug" property
boot cd:,\\:tbxi
There is a universal image of the community in the dvd-drive.
Mac OS was booted with bus errors:
But after the computer stood overnight in sleep mode in OS X 10.4, the boot of Mac OS 9 broke down again, and shows nothing but a gray screen.
Some suggest that can start kernel booting debug mode through OpenFirmware, and then it may become clear what is wrong with this computer.
How to enable debugging mode when booting the kernel in Mac OS 9?
