You can force  the  system to   run  in  Monochrome  Mode by
    setting   MONOCHROME   to  "Yes".    If  you   are not using
    RemoteAccess in a multi-tasking environment, then set DIRECT
    WRITE MODE to "Yes".   This will  cause all screen output to
    be written directly to Video RAM instead of using BIOS calls
    and will result in a significant speed increase.  If you use
    one of the older CGA cards that is  prone  to "snowing", set
    SNOW CHECK to "Yes".
