ABSTRACT:
A virtual DOS monitor uses the paging hardware of a processor such as the Intel 80386 microprocessor in conjunction with its Virtual-8086 mode of operation to emulate expanded memory using extended memory. Support for application programs which access expanded memory is thereby provided without the need for additional memory boards or other hardware.
