Here they are! 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)
Acumos, Ahead, Avance Logic 2101, ATI, Chips & Tech, Cirrus Logic, Compaq,
Everex, Genoa, MXIC68000, NCR, Oak, Primus 2000, Paradise, Realtek, S3
Trident (both 8800 and 8900, 9000), Tseng (both ET3000 and ET4000) 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 Tseng ET4000,
S3 and Paradise cards, and have had no problems.
Cards with occasional problems: (try using a VESA driver)
Trident
OAK
----------------------------------------------------------------------------
*NEW* BGIv3.0 drivers support protected mode under Borland Pascal 7.0.
Registration fees cover both v2.0 and v3.0 source code.
Any current Borland/Turbo Pascal or C/C++ compiler can use BGIv2.0
in real mode. Only Borland Pascal 7.0 and Turbo Pascal 7.0 currently
support BGI v3.0; Borland Pascal 7.0 needs BGIv3.0 to work in
protected mode. The BGIv3.0 drivers are in the \BGI30 directory.
----------------------------------------------------------------------------
Modes currently supported:
SuperVGA 16-color
0) Standard EGA/VGA 320x200x16
1) Standard EGA/VGA 640x200x16
2) Standard EGA/VGA 640x350x16
3) Standard VGA 640x480x16
4) SuperVGA/VESA 800x600x16
5) SuperVGA/VESA 1024x768x16

SuperVGA 65536-color
0) 320x200x65536
1) 640x350x65536
2) 640x400x65536

4) 800x600x65536
5) 1024x768x65536
6) 1280x1024x65536
* WARNING: The tweaked drivers do not use standard BIOS modes, instead
they program the CRTC directly. You must have a register-compatible
VGA card to use these drivers. You must also be sure that your monitor
can handle the sync rates (the sync COULD damage your monitor)

6) 1280x1024x16
7) 640x480x32768
----------------------------------------------------------------------------
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 the drivers. This is because
no current mouse drivers support SuperVGA/Tweak modes. See the MOUSE\
directory for beta drivers with built-in mouse support.
* Registerfarbgidriver DOES work properly with C/C++... (8/1/91)
Check INITSVGA.C and the makefile for examples of how to use.
* Registerbgidriver also works with Turbo Pascal. Check the file NEWINIT.PAS
for an example.
* Imagesize does not work. (the kernel does not call the drivers to do this)
Use the following formulas:
* imsize = ((xwid >> 1)+1)*ywid+4; (16-color)
* imsize = xwid*ywid+4; (256-color)
* imsize = 2*xwid*ywid+4; (32768/65536-color)
* The .CHR files needed by the VGADEMO program are version 1.00 (dated
October 1987), so if the fonts do not work properly with the demo program,
you are probably using the newer fonts (eg. 1.1 dated June 1989 do not work
properly). This is a fault of the BGI kernel that the demo program was
compiled with (Turbo Pascal 5.5 doesn't recognize the newer version)
* If nothing appears on the screen when you draw in 256/32k modes, try
setting the draw color to white (15 on Svga256, see notes.32k for Svga32k)
The BGI kernel sets the initial draw color to the maximum color (255),
which is usually black.
----------------------------------------------------------------------------
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. :->

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.
(Note: This library is NOT a BGI driver. It attempts to fix some of the
problems I've found with the BGI kernel, ie. the number of colors is
limited to 256 in the BGI kernel)
(Current library is non-functional)
