Installing Leopard on Machines under 867MHz
Without using LeopardAssist
Today, I'll show you how to install Leopard 10.5 on a machine under 867MHz using Open Firmware.
What you will need:
Leopard Installation Media
A G4+ machine with a supported graphics card and 512MB+ RAM
Note: Before attempting to install Leopard, make sure your firmware is up-to-date. On most PowerPC machines,
firmware updates must be native in Mac OS 9. Check here to see if one is available.
Also, if you are using an external Hard Drive or thumb drive, make sure to select that as your boot drive before starting Open Firmware.
Remember, playing around with Open Firmware is not recommended.
For those with 667Mhz PowerBooks (Or possibly other Macs that don't work with LeopardAssist): 1.) Place the 10.5 Install disk in your drive. 2.) Restart your Mac (don't use on the installer on the disk) 3.) After the chime, hold down COMMAND+OPTION+O+F until you see a light gray screen with black text.
