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. -- Stephen M.
