-
- This Device Driver will relocate EGA ROM at Address C000:0000
- to RAM, and fix up the vector table to point to the "Shadow RAM". This
- will be of benefit to 16 and 32 bit machines (8086/80286/80386) that are
- slowed by 8 bit access to the EGA Video Adapter Card. Since this
- Driver searches the low memory vector table for references to the
- EGA ROM BIOS Segment it MUST be the first Device entered in your
- CONFIG.SYS file (Device=RAM4EGA.SYS). If EGA ROM BIOS is not found at
- Address C000:0000 it will do nothing, otherwise it will dramatically
- speed up Video BIOS Routines. As always, use this at your own risk,
- however, I would be interested in hearing about any problems.
