  • Method for distinguishing between a 386-type central processing unit and A 286-type central processing unit
    Patent number: 5490267
    Abstract: A method is disclosed for distinguishing between the Intel 80386 and 80286 CPUs. Bits 12, 13, and 14 of the 386 flags word in the real mode are always zero in the 286 architecture and cannot be set, but can be set to a one on the 386. The method includes the steps of attempting to set any of those bits and examining the results. A source code listing is attached.

  • Software emulation of bank-switched memory using a virtual DOS monitor and paged memory management
    Patent number: 4926322
    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.
