no, no, no, DO NOT enable chipmem cacheing unless you have a gfx card! It's highly unlikely that you have a gfx card on the A600.

Back when Oliver introduced the feature in the logic, I thought that CPUblit completely switches off the blitter, but in the meantime I learned that only a few functions are replaced with CPU copy-functions. Other functions still use the blitter. If I had known that back then, the function would not be in the card. Chipmem cacheing is a bad idea with a second entity writing to chipmem - the cache would have to be invalidated on a blitter-write, but that cannot be detected on the CPU card.
