X-Hacker.org- Assembly Language - <b>0:466h current setting of the color select register (port 3x9h)</b> http://www.X-Hacker.org [<<Previous Entry] [^^Up^^] [Next Entry>>] [Menu] [About The Guide]
0:466h                   Current setting of the Color Select Register (port 3x9h)

 Length: 1 byte

    Contains the current setting of the Color Select Register (port 3x9h)

  --------------------------------------------------------------------------

    Depending upon which CRT controller is currently active, this value
    could reflect either the contents of:

                  3B9h for Monochrome, or
                  3D9h for Color Graphics Adapter

    Since the Monochrome display adapter reserves port 3B9h, this byte
    will reflect the value of 3D9h for the CGA, and will not be used for
    the monochrome display adapter (but it could in the future).
