disktransfers: +always use page 2 or 3 (#8000-#fffe) +In MSX-DOS (1&2) environment it is also possible to pass parameters in page 0 and 1, but it is slower (diskrom needs additional slotswitching) +Always make sure that the transferarea is located in the primary ramslot. (in the official way you can obtain the mainramslot with the DOS2 extended biosfunction (see section 5.2)) I don't know in DOS1... But we all know (?) that this info is also located on address #f341/2/3/4, both DOS1 and DOS2. Why they made 4 locations with the same value is a mystery to me. probably overdesigning before the memorymapper age... (also the official DOS2 docs say (also section 5.2, last lines) that the slotselection of all 4 pages is the same.)
