I think that you Does it mean LIM expanded memory area must be read through the LIM window? and it must be MAPPED the same CPU address space (page frame address) ? > can see what this copying would do to software that expected to be able > to modify the SAME block of memory at two addresses. :-( > -russ I am looking for a LIM driver implemented by software emulation. Is there anyone who made LIM emulation driver for 80286 or 80386 ? I heard there is a LIM emulator using 80386 protection mode or exception or virtual mode or another function. Please let me know such kind of LIM driver. And please post in net, not by mail. Thanks, Yutaka Matumoto z34%.kyocera.junet@uunet.uu.net

PC Magazine reviewed these emulators about 14 months ago, can't locate exact issue offhand. Have not personally used any of these.
