SetPatch runs as the first command in the Startup-Sequence when Amiga boots up. It applies patches to the code in ROM to fix bugs and also enable features if necessary. For example, I seem to remember that the advanced fetch modes for Chip RAM DMA under AGA only get enabled by SetPatch and/or IPrefs.
Is there a list detailing exactly which patches each version of SetPatch applies and under which conditions?
