     My EGA has 256K bytes on it of which I probably only use a fraction
for my monochrome display.  I wonder if it is possible to use some of the
memory on the EGA card to store data while I am not using any of the 
graphics modes.

     Does anyone know if this is possible?  How does the EGA memory
map into the PC memory map?   Is it bank switched?  I know some of it maps
to where the display memory on the EGA's predicessor cards goes, but all 256K?

     Any help would by muchly appreceated.   Thank you.
