SUMMARY
=======

Although the ANSI.SYS device driver allows changing of foreground, background,
and text attributes, it does not change the border color. However, there is a
ROM BIOS interrupt call that allows the border color to be changed if your ROM
BIOS supports it.

MORE INFORMATION
================

The ROM BIOS interrupt 10H contains the ROM BIOS video services. Subservices 0BH
or 10H should be used, depending on the graphics adapter installed. The
following is a partial assembly-language code example of how to set the border
color using these ROM BIOS video subservices:

      ; For CGA:
      ;
      mov  ah,0BH  ; video subservice 0BH: set palette
      mov  bh,00H  ; palette subservice 0: set border
      mov  bl,06H  ; color = 6
      int  10H     ; call ROM BIOS video interrupt 10H
   
      ; For PCjr, EGA, VGA, and MCGA:
      ;
      mov  ah,10H  ; video subservice 10H: set palette
      mov  al,01H  ; palette subservice 1: set border
      mov  bh,06H  ; color = 6
      int  10H     ; call ROM BIOS video interrupt 10H
