i already know how to get into svga mode (640x480x256 ... 5 banks) using
DJGPP, but i want to know how to have a buffer for the screen (307,200
bytes) so it would work like this:
1) i would draw to the 307,200 buffer
2) during retrace i would draw 64K to the first bank, switch banks, draw
the next 64K, etc until the entire buffer had been transfered to the
screen.
i tried to create a program that did this, using a near pointer to the
screen, but after it finished drawing to the first bank, it restarted my
computer. any suggestions?
