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 (80286/80386).

RAM4EGA Version 1.10
(C) 1988 - DLF Solutions!


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 (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.
