talk to imic.. hes the man
Yes it is, but he has already told us how to do it:
The Open Firmware Patch:
" /cpus/PowerPC,G4@0" find-package if drop " /cpus/PowerPC,G4@0" find-device 80010201 encode-int " cpu-version" property then
device-end \ PLX-OS9-PATCH
Were
80010201 (PPC 7455) should be changed by one of this:
PowerPC 7400_v1.0 PVR 000c0100
PowerPC 7400_v1.1 PVR 000c0101
PowerPC 7400_v2.0 PVR 000c0200
PowerPC 7400_v2.1 PVR 000c0201
PowerPC 7400_v2.2 PVR 000c0202
PowerPC 7400_v2.6 PVR 000c0206
PowerPC 7400_v2.7 PVR 000c0207
PowerPC 7400_v2.8 PVR 000c0208
PowerPC 7400_v2.9 PVR 000c0209
Probably PowerPC 7400_v2.9 PVR
000c0209 because It is the best PPC Mac Os 8.6 can deal with.
And we have to enable also the PowerMac 3,3 (Gigabit Ethernet) PowerMac 3,4 (Digital Audio) PowerMac3,5 (Quicksilver) etc... In the Mac Os 8.6 ROM file.
