There are two possibilities, and I've seen both.. one allows you to make the normal RAM not cover a region, (say 12-16MB) even though yop have more, so you can stick a frame-buffer card there.. the other puts a hole in the shadow ram that covers the 640K->1MB IO area, so you can have an IO card with shared ram there.. (otherwise you just see your ram and not the ram on the card..) especially bad with ETHERNET CARDS..
