<p>A system for selectively controlling (41, 48) individual expansion slots in an IBM-AT/NEC 9801 dual-compatible computer provides automatic control for the individual ISA bus expansion slots (18, 25) in the computer. This facilitates the use of an Industry Standard Architecture (ISA) bus (10, 11) and ISA (AT) type add-on cards in the dual compatible computer. A user configures each slot as containing either a card which may interfere with operations of the computer in the non IBM-AT compatible mode or a card which will not interfere with computer operations in the non-IBM-AT compatible mode. Thereafter, the computer automatically disables the cards in accordance with the mode of computer operation.</p> |
