* 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 braindamaged 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.

* Added support for Vesa. It is not complete but is a start.
|

* Currently i dont have a program that uses Vesa that actually gets far
|
|
* enough without crashing to do vesa stuff.
