| * Handler for int 10h (video). |
| * |
| * NOTE: |
| * Most INT 10 functions for text-mode, CGA, EGA, and VGA cards |
| * are present in this list. (SVGA and XGA are not) That is not |
| * to say that all these functions should be supported, but if |
| * anyone is brain-damaged enough to want to emulate one of these |
| * beasts then this should get you started. |
| * |
| * NOTE: |
| * Several common graphical extensions used by Microsoft hook |
| * off of here. I have *not* added them to this list (yet). They |
| * include: |
| * |
| * MSHERC.COM - More functionality for Hercules cards. |
| * EGA.SYS (also MOUSE.COM) - More for EGA cards. |
| * |
| * Yes, MS also added this support into their mouse driver. Don't |
| * ask me, I don't work for them. |
| * |
| * Joseph Pranevich - 9/98 |
| * |
| * Jess Haas 2/99 |
| * Added support for Vesa. It is not complete but is a start. |
| * NOTE: Im not sure if i did all this right or if eny of it works. |
| * Currently i dont have a program that uses Vesa that actually gets far |
| * enough without crashing to do vesa stuff. |
| * |
| * Added additional vga graphic support - 3/99 |
