The idea is to use a certain address space, which is cached. Thus, you don't have to have real memory there, it is all in the cache anyway. They chose CS4 to make sure that even if something goes to the bus, there are no unpleasant side effects, since CS4 is not used. As I said in the previous email, I also had some problems using this piece of code and quickly moved on to use OCM, just because I knew that another bootloader used it anyway. Happy hacking, Vladimir
