58 * DOSVM_Int10Handler (WPROCS.116)
60 * Handler for int 10h (video).
63 * Most INT 10 functions for text-mode, CGA, EGA, and VGA cards
64 * are present in this list. (SVGA and XGA are not) That is not
65 * to say that all these functions should be supported, but if
66 * anyone is brain-damaged enough to want to emulate one of these
67 * beasts then this should get you started.
70 * Several common graphical extensions used by Microsoft hook
71 * off of here. I have *not* added them to this list (yet). They
74 * MSHERC.COM - More functionality for Hercules cards.
75 * EGA.SYS (also MOUSE.COM) - More for EGA cards.
77 * Yes, MS also added this support into their mouse driver. Don't
78 * ask me, I don't work for them.
80 * Joseph Pranevich - 9/98
83 * Added support for Vesa. It is not complete but is a start.
84 * NOTE: Im not sure if i did all this right or if eny of it works.
85 * Currently i dont have a program that uses Vesa that actually gets far
86 * enough without crashing to do vesa stuff.
88 * Added additional vga graphic support - 3/99
