About this patch…
This is version 1.0 of Output Enablers' System 7.5 Update Patch.  It is free, and may be distributed over the Internet and public online services.  It MAY NOT be distributed by any Clock Accelerator company other than Output Enablers, although owners of kits from those companies (Newer Technologies, KS Labs, Other World Computing, Trinity Works, DVC, etc.) are allowed to use the program free of charge.

How does it work?
Apple's new System 7.5 Update 1.0 contains code to selectively load Operating System patches based on machine type. Machine type is determined at boot-up and is stored as a "Gestalt" value. PowerMacintosh 7100/66 machines that have been upclocked to 80 MHz report a different Gestalt value than either the standard PowerMac 7100/66 Gestalt or the 7100/80's Gestalt.  Hence, the System Update 1.0 will not load on 7100/66's that have been upclocked to 80 MHz.

OE's patch to the System Update 1.0 file simply copies certain resources for the normal 7100/66 and changes the resource ID to match the Gestalt value of the upclocked 7100/66.

A similar patch is included for PowerMac 8100/100 and 8100/110 machines that have been upclocked past 120 MHz.
