39 * Handler for int 10h (video).
42 * Most INT 10 functions for text-mode, CGA, EGA, and VGA cards
43 * are present in this list. (SVGA and XGA are not) That is not
44 * to say that all these functions should be supported, but if
45 * anyone is braindamaged enough to want to emulate one of these
46 * beasts then this should get you started.
49 * Several common graphical extensions used by Microsoft hook
50 * off of here. I have *not* added them to this list (yet). They
53 * MSHERC.COM - More functionality for Hercules cards.
54 * EGA.SYS (also MOUSE.COM) - More for EGA cards.
56 * Yes, MS also added this support into their mouse driver. Don't
57 * ask me, I don't work for them.
59 * Joseph Pranevich - 9/98
62 * Added support for Vesa. It is not complete but is a start.
63 * NOTE: Im not sure if i did all this right or if eny of it works.
64 * Currently i dont have a program that uses Vesa that actually gets far
65 * enough without crashing to do vesa stuff.
67 * Added additional vga graphic support - 3/99
