I think MergeMem is simple enough that if the addresses ("address space") used by the memory in the expansion product are contiguous to the addresses used or covered by the other Amiga memory, the memory will be merged into one piece. One of (or maybe the only) time MergeMem is needed, if I remember, is when you use a memory expansion device that does not "autoconfigure." Some memory expansion products don't. A slight correction: I have a Supra 8 meg expansion card with 6 megs populated. I don't know why, but somehow the expansion card makes the computer to believe that there are actually two expansion cards, one 4 Meg and one 2 Meg. They are both autoconfig, but after the boot my A2000's largest contiguous memory hunk is 4 Megs. But now, if I run MergeMem, I suddenly have 6 Megs of contiguous memory, since these two pieces will be merged. The point is, that MergeMem is useful also with some autoconfig memory boards. Btw, how about if you have two memory expansion cards? Can they be merged? Anyone?
