[comp.sys.ibm.pc] EGA memory configuration

toms@oakhill.UUCP (Thomas Spohrer) (07/23/87)

     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.

Do you mean that your EGA card talks TTL? Is this true for most (all) EGA
cards? What kind of card are you using? If they generaly talk TTL then I
just found the answer to my problem.

Thanks,
Rob
