opening JP7A on the A500 or JP1 on the A501 will disable the memory.

regarding "turning off" in software, you could unlink the memory lists, allocate all of it, etc.. most games, etc, will probably look for slowfast by checking MaxExtMem in execbase.

Ok. I have a code which allocates as much fastmem as possible, which works i most cases, but not all. Thanx for the answer. Some demos in my Collection doesn't like fast, so that's why i needed to know.
