On a related note, does anyone know the capabilities of the VLSI chip
set used in 286 motherboards?  My no-name board manual (there's a
wireframe picture of the space shuttle on the box) says VLSI has
software to map extended memory to expanded but the dealer I got it
from claims there is no such thing and to use QRAM.  Well, I tried QRAM
and the various mappers from SIMTEL with no luck.  Nothing in the CMOS
setup or on the motherboard switches either.

An expanded memory board that I have won't work either because the ROM BIOS
uses from E000-EFFF for diagnostics code in addition to the normal Fxxx range.
Other stuff uses the rest except for D000-DFFF which isn't enough for the
EMM board EPROM and the 64K page frame (3.2, not 4.0).

Any ideas before I swap this thing for a C&T chipset version or a 386?
