$How many of the 386/AT motherboards out there are able to assign the

$I know the DTK/386 20Mhz motherboard (with a DTK BIOS) can do it.
$However, I haven't seen any other motherboards used by low-end clone
$makers that claim this capability. If you believe the sales people in
$the stores I went, once you disable the ROM shadowing in their machines
$those memory locations (the top 384K) are lost.
The Suntac AT motherboard does this, too. You can select any memory
above 640K to be either extended or expanded ... it has no shadowing
option (at least, not the motherboard I have, which I bought about a
year and a half ago).
A friend of mine has a couple of ATs (I don't know what brand their
motherboards are) which are also capable of using memory above 640K
as extended memory.
