I am trying to find out some technical info on the EGA mode. Specifically I want to know how to store a picture into the video memory so that it looks the way it should. I will be reading a 64k file that is 320x200 with 16 colors (4 bits of 8 used). I know the video memory starts at A0000 and is probably in banks of 8k. Each bank of 8k corresponds to one of 4 bits for 16 color mode. The banks are called bitplanes and all of them start at A0000. So, how do I switch from one bitplane to the next? Doing EGA stuff in BIOS would be pathetically slow. All I really want to do is screenload a picture so direct memory copy seems like the fastest way to do it. -- Jeff Capehart Internet: jdc@beach.cis.ufl.edu University of Florida UUCP: ..!uflorida!beach.cis.ufl.edu!jdc
