Here it is! The SuperVGA/Tweak BGI drivers you have all been waiting for! ;->

  These drivers support a wide range of VGA cards, and should work on
all major brands.

Card types supported: (SuperVGA drivers)
  Ahead, ATI, Chips & Tech, Everex, Genoa, Paradise, Trident (both 8800 
and 8900), Tseng (both 3000 and 4000 chipsets) and Video7.
  These drivers will also work on video cards with VESA capability.
  The tweaked drivers will work on any register-compatible VGA card.

I have not tested these drivers on all these card types, so I can not guarantee
perfect operation with your card.  I have tested them extensively
on Trident, Tseng and ATI cards, and have had no problems. (Trident 8800
cards occasionally have problems, especially older models)

Modes currently supported:
  SuperVGA 16-color
   0) Standard EGA/VGA 320x200x16

   3) Standard VGA 640x480x16
   4) SuperVGA/VESA 800x600x16
   5) SuperVGA/VESA 1024x768x16

  SuperVGA 256-color

----------------------------------------------------------------------------
INSTALLATION:
  Using the driver in existing programs is easy. (If you have the source)

  Check the files INITSVGA.C and INITSVGA.PAS for examples of installation
into C and Pascal programs.

----------------------------------------------------------------------------
NOTE: 

 - The mouse cursor may not work in all modes of my driver.  This is because
   most mouse drivers do not support SuperVGA/Tweak modes.

 - The registerbgidriver(*) function does not work. This is due to a limitation
   in the BGI kernel, which checks the linked in driver with a list of the
   standard BGI drivers (CGA,EGAVGA,etc..), and if it is not one of those,
   will not use the linked in driver.

 * However, registerfarbgidriver DOES work properly with C/C++... (8/1/91)
   Check INITSVGA.C and the makefile for examples of how to use.

 - Imagesize does not work. (the kernel does not call the driver to do this)
   Use the following formula:
    * imsize = ((xwid >> 1)+1)*ywid+4; 	(16-color)
    * imsize = xwid*ywid+4; 		(256-color)

----------------------------------------------------------------------------
WARNING: The drivers do not test to see if the card installed is
actually a VGA card (If the Svga drivers do not detect a SuperVGA card, they 
treat the card as a standard VGA), so DO NOT use the drivers if you do not 
have a VGA card installed.

-------------------------------------------------------------------------
REGISTRATION:
  I have decided to release these drivers free of charge,
although donations would be greatly appreciated and certainly
expedite the release of future versions. :->
  The drivers have not been crippled in any way, though beta releases of new
drivers may have some functions yet unimplemented.  

Registration fees:

	SuperVGA 256 			$20
	SuperVGA 16			$20
	Tweak 16			$20
	Tweak 256			$20

	Any two:			$30
	All 4:				$50

With donations of $20 and up, you will be considered a registered user.
Registered users get the full source code and upgrades on future releases.

I have started working on a new graphics library that will support resolutions
from 160x200 (Ick! ;->) all the way up to 1280x1024, and from 1-bit color
to 24-bit color.  It will support a wide range of cards and I need testers
for XGA/8514/Hercules Graphics Station cards.
