I tried today to write characters to an EGA screen today while in mode 16
(350x640x16 colors graphics) using the bios INT 010H, AH = 9, which is
write attribute/character. This works fine in mode 3 (24x80 text) but
in mode 16 it writes the character correctly, but refuses to do anything
with the color attributes. It writes white on black. Does anyone know if
it can be made to write in an arbitrary color? I have a graphics drawing
routine to do it, but using the BIOS should work ... or should it?
