INT 43H: EGA/VGA Graphics Character Font Pointer


 This vector (0:010c) is a pointer to a table of Font Definition Data that

 defines all ASCII characters that will be used to display text (via

 INT 10H 0eH et al.) while in graphics mode on EGA and VGA video systems.



 A copy of a font is maintained is easily-accessible memory (usually ROM)

 to that BIOS fns such as INT 10H 08H (read character from screen) can

 compare sets of graphics pixels against the defined characters in order to

 return an ASCII value.



 See Font Definition Data for a layout of this data.  The size of the

 entries (bytes-per-character) varies according to the value in 40:0085

 (see BIOS Data Area).
