The SVGA256.BGI driver provided here is the property of Jordan Powell Hargrave. The driver is provided here only for evaluation. The driver is provided so that Turbo C and Turbo Pascal users can use it to display the 256 color XGF files. The following is the actual readme file distributed with the entire series of drivers released by Jordan Hargrave. ************************************************************** COPYRIGHT 1991, JORDAN HARGRAPHIX SOFTWARE PORTIONS COPYRIGHT JOHN BRIDGES, 1990 CHRISTOPHER MORGAN, 1984 ************************************************************** 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, Oak, Trident (both 8800 and 8900, 9000), 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 1) Standard EGA/VGA 640x200x16 2) Standard EGA/VGA 640x350x16 3) Standard VGA 640x480x16 4) SuperVGA/VESA 800x600x16 5) SuperVGA/VESA 1024x768x16  SuperVGA 256-color 0) Standard VGA/MCGA 320x200x256 1) 256k Svga/VESA 640x400x256 2) 512k Svga/VESA 640x480x256 3) 512k Svga/VESA 800x600x256 4) 1024k Svga/VESA 1024x768x256 5) 256k Svga 640x350x256 6) 1280k+ VESA 1280x1024x256 * NEW SuperVGA 32768-color BGI driver for Tseng ET4000 and ATI XL cards with Sierra HiColor DACs  SuperVGA 32768-color 0) 320x200x32768 1) 640x350x32768 2) 640x400x32768 3) 640x480x32768 4) 800x600x32768 * 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)  Tweaked 16-color 0) 704x528x16 1) 720x540x16 2) 736x552x16 3) 752x564x16 4) 768x576x16 5) 784x588x16 6) 800x600x16  Tweaked 256-color 0) 320x400x256 1) 320x480x256 2) 360x480x256 3) 376x564x256 4) 400x564x256 5) 400x600x256 6) 320x240x256 * New SuperVGA driver for S3 cards. (Orchid Farenheit 1280, Diamond Stealth) Uses extended features of the S3 chip to provide enhanced performance.  S3 Accelerator 16/256/32768-color 0) 640x480x256 1) 800x600x256 2) 1024x768x256 3) 800x600x16 4) 1024x768x16 5) 1280x960x16 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 my driver. This is because no current mouse drivers support SuperVGA/Tweak modes. * 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 driver 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-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. :-> The drivers have not been crippled in any way, though beta releases of new drivers may have some functions yet unimplemented. Registration fees: SuperVGA S3 $20 SuperVGA 32768 $20 SuperVGA 256 $20 SuperVGA 16 $20 Tweak 16 $20 Tweak 256 $20 Any two: $30 Any three: $40 Any four: $50 Any five: $60 All six: $70 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. From September 1-May 8, please send checks/money to: Jordan Hargrave 1000 Morewood Ave, Box #3277 Pittsburgh, PA 15213 (412) 268-4493 From May 8-September 1, send to: Jordan Hargrave 1615 Burnley Road Charlotte, NC 28210 (704) 553-2332 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) *===============================*===========================================* | Jordan Powell Hargrave | Internet: jh5y@andrew.cmu.edu | | 1000 Morewood Ave, Box #3277 | Bitnet: jh5y%andrew.cmu.edu@cmccvb | | Pittsburgh, PA 15213 | UUCP: uunet!andrew.cmu.edu!jh5y | | (412) 268-4493 | Compuserve: [72510,1143] | *===============================*===========================================*
