LeopardAssist originated from LowEndMac in Dylan McDermond's December 6th 2007 post "Faking Out the Leopard Installer with Open Firmware". The simple techniques he used in that article became the basis for the structure we were about to use.
LeopardAssist does just what was posted in his article. Using a temporary Open Firmware "trick", it changes the reported CPU speed to 867mhz and starts the installer from CD.
The application writes a script into your computers Parameter RAM (PRAM) changing the CPU entry in the device tree to 867mhz. On restart, Open Firmware loads as normal with the 867mhz script in place, switches to CD or DVD and boots from it, where the Leopard installer takes over.
This simple trick means you don't have to modify your DVD to install Leopard. Finally, when installation is done or when installation is ready to reboot, you simply flash the PRAM back to restore the original CPU speed and restore booting from the hard disk.
Now you can easily install OS X Leopard on that old 800MHz G4...
