Technically, they can't have extended memory. It's the memory above the 8086/8088's 1 meg limit. They can have some memory in the 640k to 1M range, but as this area is intended for add-in card memory it's really not too useful for other purposes, and there's no standard place to always find empty. Maybe you're thinking of expanded memory? That was developed *before* protected mode made it unnecessary...when you have >1 meg address space, there's no point. Those cards are pretty uncommon too, I would say that there are probably more important things to spend development time on :) Dan
