Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     Each attribute byte in the video buffer corresponds to a specific
     character position on the screen. Bits 4-7 determine the
     character's background color and blink state. Bits 0-3 determine
     the foreground color and brightness.
