Does anyone out there know how to read from and write to the extended memory
addresses of ibm and compatibles.  The addresses I am specifically trying to
get to are E00000 through EEFFFF (hex).  The TP4 direct memory access 
procedures will only work for the under 1Meg boundary.  I would like to
avoid using BIOS calls if at all possible (they are too slow) since I am doing
a lot of memory access.

                    Thanks in advance.
