On the contrary, I don't know of any way to do it on a PC motherboard,
but the PC portable has a standard XT board.  Instructions have been
published in a variety of magazines and BBS's to upgrade the XT board.
I don't have the details on hand, but the procedure requires adding a
jumper to a pair of pads located by the power connector, plugging a
chip into an empty slot (from memory (ugh!), 74ls158 in u86?), and
changing the memory chips to 256K type.
