Hello Netlanders,

Does anyone know the different video mode numbers, the corresponding
effect and the memory organization for the IBM EGA card?

In effect, I need to know what memory address corresponds to each video mode
so that I can place a bit map on the screen buffer (It's for a clock
in the upper right hand of the screen that will operate in graphics mode 
i.e., with Word and Autocad. I already got it to work in 640x200 mode of
my cga, but sometimes I use an EGA)

ADthanksVANCE
