From the developer:
LeopardAssist is a simple tool to install Leopard on older, unsupported Power Macs.
It bypasses the 867 MHz processor check in the Leopard installer to allow systems that don't meet the requirements to complete installation. It achieves this by temporarily faking the clock speed in the device tree, changing it to 933MHz, and then launching the Leopard Installer.
You may want to check out more Mac applications, such as Macfilink, PodManager or iPhoneDisk, which might be similar to LeopardAssist.
