Default unused UMB areas to be read-only. It looks like MSDOS 6 wants the UMB area to be read-only in order for it to use it. FreeDOS doesn't care, but it always maps a page from high mem when it does use the area. So, add an option to control whether unused UMB ram is marked read-only and default it to read-only as that seems to be more compatible. This also fixes an off-by-one bug in the shadow range checking code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
