Abstract
A hardware system provides a programmable method for addressing expanded memory specification (EMS) registers in a personal computing system functioning with an MS-Dos.RTM. operating system or the like. The system provides hardware flexibility for addressing EMS registers at different addresses than the standard LIM EMS specification calls for, to permit utilization of register addresses in otherwise unavailable locations. The address translations are effected through hardware; so that no additional delays in the circuit operation occur.
