MNMIHEEM.SYS
                         INSTALLATION INSTRUCTIONS


INTRODUCTION:

    MNMIHEEM.SYS is a program executed from CONFIG.SYS that allows an IBM 
    EGA adapter to function properly in any Compaq 486-based system.


SYSTEM REQUIREMENTS:

    Any Compaq system that:
         1.  Uses an Intel 486 processor.
         2.  Has an IBM EGA adapter installed.
         3.  Uses DOS version 3.0 or newer as its operating system.


WHO SHOULD USE:

    When an IBM EGA adapter is placed in a Compaq 486-based system, three 
    beeps (one very long, two long) occur during initialization.  The 
    machine then boots in 40-column mode.  In an MS-DOS environment, the 
    adapter can be returned to 80-column mode by typing MODE CO80 from a 
    DOS prompt, however, all EGA functionality is NOT regained.


HOW TO USE:

    Copy the file MNMIHEEM.SYS to the disk or diskette you will be booting 
    from, using the DOS copy command:

         copy a:\mnmiheem.sys d:\path\mnmiheem.sys

    where d:\path\mnmiheem.sys shows the drive and directory in which the 
    program is to be stored and the device from which to boot.

    Using the file editor of your choice, place the following line as the 
    first line in the CONFIG.SYS file:

         device=d:\path\mnmiheem.sys.

    When the system boots, the beeps described above still occur, but 
    shortly thereafter the screen goes blank for a short period and then 
    displays in 80-column mode.  No installation messages are given.

EFFECTS ON YOUR SYSTEM:

    After re-initializing the EGA adapter, this program leaves no residue 
    in your system.
