Hello World

SkyCapt

How To
Change a Mirror Door G4 to a Mirror Door G5,
with this sequence of commands:

boot into Open Firmware mode, then
type the following exactly as it appears including the white space. First you may elect to type dev / .properties where you can optionally watch what happens before and after.

nvedit
dev /
" PowerMac7,2" encode-string " model" property
" PowerMac7,2" encode-string " MacRISC2" encode-string encode+ " MacRISC" encode-string encode+ " Power Macintosh" encode-string encode+ " compatible" property

press [ctrl^l] to list this script you've just typed.
press [ctrl^c] to leave the script editor.

nvstore
setenv use-nvramrc? true
reset-all

Done. After loading Mac OS, Mac OS X, or AHT, the machine will report itself as PowerMac G5 not G4, and if you possess the correct hardware it will accelerate accordingly. This method assumes you weren't using the nvscript for any other purpose, if so you will need to combine your two scripts. Execution of the PRAM-Reset will destroy the script and return the machine to factory default settings. One quick method for toggling between G4 and G5 modes is to just type "setenv use-nvramrc? false" (followed by reset-all, for G4) then, "setenv use-nvramrc? true" (followed by reset-all, to return to being G5).

As far as I can see, acceleration requires more than 2 GB RAM installed, and Tiger OS not Leopard OS.
Panther 10.3 (my least favorite) accelerates with this firmware script, and Jaguar 10.2.8 and 10.2.7 accelerate very well but only when you use the "G5" edition of Jaguar and it will do it even without this script, the OS X that came to be branded "Smeagol". Smeagol has the greatest Classic Mode of all Classic Modes, and a good hardware accelerated OpenGL.

I have special G4-G5 hybrid Mac system, the greatest PowerPC model.
Internet refuses to admit this mass produced machine even exists.
AGP-16x DDR 467MHz RAM 1.58GHz G4 CPU
2.25 GB RAM capacity (more than 2.0GB y'all!)
Disabled all or most of "slowram taxes" on memory - anti ram bandwidth. [i must elaborate someday]
Graphics card: Core Image modest ATi Radeon 9600 Pro 64MB
1920x1200 display, whole lot better than 1920x1080
Disabled "Beam Sync" in Tiger & Leopard. [i must elaborate]
