|

* Several common graphical extensions used by Microsoft hook
|

|
|

|
|
* 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

|
* 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
