The SuperVGA Test Library ------------------------- The SuperVGA Test Library is a set of routines for automatically detecting a number of different SuperVGA chipsets, and performing bank switching and extended page flipping on supported SuperVGA's. It will also detect the presence of HiColor and TrueColor video DAC's and provides support for video modes that use these DAC's. This library supports many of the extended features of today's SuperVGA adapters, such as being able to separately set the read and write banks and support for extended page flipping. Not all of these features are available on each SuperVGA, but providing support for them if they are available is made extremely easy. NOTE: All source code is formatted with 4 space tabs, including the assembly language source. NOTE: This library has '386 specific code in it, so it will _not_ work with machines without a '286 or lower processor. Using it in your own programs ----------------------------- There are two options you can use to include this stuff in your own programs. You can simply write you code to work with any VESA compatible SuperVGA card, and require that users of your programs load the Universal VESA TSR or something equivalent before use. Or alternatively, you can use the code directly to gain even higher performance. To make this even easier than before, I have built a number of libraries you can simply link into your code (tested with Borland C++ 3.1), and the corresponding header files. The routines are pretty basic, so check the code for documentation on how to use it (and see the test programs for ideas). Bug fixes, changes etc ---------------------- If you have a SuperVGA card that it not supported by this library, I would appreciate it if you mail me some code to to add support for your video card. If your video card supports extended page flipping or separate read/write banks, but support for this is not included in the library, I would apprecite it if you mail me some code to add support for this to the library also. Also, if the library misbehaves on your system, I would appreciate feedback on the problem so we can attempt to rectify it (see the list of cards that have been successfully tested, before mailing me a yes answer :-). I would appreciate it if people could fill in the following form and mail it back to me (see the read.me for for more details). ---------------------------------------------------------------------------- Name: ____________________________________________________ Email: ____________________________________________________ Library Version: ___________ SuperVGA board: ___________________________________________ Chipset Type: ___________________________________________ Demo Results: 16 color demo: Ran Correctly [ ], Incorrectly [ ], Unsupported [ ] If incorrectly, which parts did not work correctly: Bank Switching [ ], Separate read/write banks [ ], Page Flipping [ ] Explain: __________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ 256 color demo: Ran Correctly [ ], Incorrectly [ ], Unsupported [ ] If incorrectly, which parts did not work correctly: Bank Switching [ ], Separate read/write banks [ ], Page Flipping [ ] Explain: __________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ 32k color demo: Ran Correctly [ ], Incorrectly [ ], Unsupported [ ] If incorrectly, which parts did not work correctly: Bank Switching [ ], Separate read/write banks [ ], Page Flipping [ ] Explain: __________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ 16m color demo: Ran Correctly [ ], Incorrectly [ ], Unsupported [ ] If incorrectly, which parts did not work correctly: Bank Switching [ ], Separate read/write banks [ ], Page Flipping [ ] Explain: __________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ ---------------------------------------------------------------------------- Test programs ------------- The library has four test programs, for 16 color, 256 color, 32k color and 16 million color SuperVGA video modes. The tests are now more informative, providing you with a menu of video modes to test, and providing feedback on what is supposed to happen. Simply run the programs and follow the instructions. Note that some video adapters support the 64k (16 bit) video modes. These are essentially the same as the 32k color video modes, but have a diffent layout for the bits in each pixel (usually 1 extra bit of green), and thus are a great cause of pain as bitmaps are not compatible between the two modes. This kit does not support the 64k color video modes (most video cards that support 64k color also support 32k colors). If any of the programs do not work correctly, you will probably see garbage on the screen or stange results (at least not what the program says should happen). SuperVGA Support: ----------------- The following SuperVGA chipsets are supported: - VESA Compatible SuperVGA's - ATI Technologies 18800, 28800 - Ahead A & B - Chips & Technologies 82c451/452/453 - Everex - Genoa Systems GVGA - OAK Technologies OTI-037C, OTI-067, OTI-077 - Paradise PVGA1A, WD90C00/10/11/30/31 - NCR 77C20/21/22E - Trident 88/8900 - Video7 V7VGA versions 1-5 - Tseng Labs ET3000, ET4000 - AcuMos AVGA2, AVGA3 - S3 86c911/924/801/806/928 - Advance Logic AL2101 SuperVGA - MXIC 86010 SuperVGA - Primus 2000 SuperVGA - RealTek 3106 SuperVGA - Cirrus CL-GD 5422 SuperVGA Extended page flipping is currently available on the following adapters: - VESA Compatible SuperVGA's - ATI Technologies 18800, 28800 - Ahead B - Chips & Technologies 82c452/453 - Paradise - NCR 77C20/21/22E SuperVGA - Trident 88/8900 - Video7 V7VGA versions 1-5 - Tseng Labs ET3000, ET4000 - S3 86c911/924/801/805/928 - Primus 2000 SuperVGA - Cirrus CL-GD 5422 SuperVGA The following adapters support separate read and write banks for faster performance in certain areas: - VESA Compatible SuperVGA's - ATI Technologies 18800-1, 28800 - Ahead B - Genoa Systems GVGA - Paradise WD90C10 and up - Video7 V7VGA version 5 or later - Tseng Labs ET3000, ET4000 - MXIC 86010 SuperVGA - Primus 2000 SuperVGA Areas needing clearing up ------------------------- - The RealTek RT3106 SuperVGA has bank switching registers in 3D6h and 3D7h. The register in 3D7h works by default for reading and writing, but there must be some way of putting this card in a mode that can use separate read/write banks. Also, I would like to figure out how to do extended page flipping on this card. - The biggest problem seems to be with the incompatible mode numbering schemes for video cards based on the ET4000 chipset with True Color video DAC's. The HiColor modes seem to be all compatible, but the True Color 640x480 24 bit mode is an add on and different cards have different numbers and methods to invoke this mode. Anyone have a solution to this problem? - The new Genoa 7900 seems to be a problem, since it uses a different mode number than other ET4000 based cards for 640x480 24 bit graphics mode. If I can figure out a way of detecting that the board is a Genoa 7900 then we can solve the problem. Anyone know how to do this? Problems -------- All S3 cards are VESA compatible, but some like the STB WIND/X have stuffed BIOSes. This driver has fixed to work with these cards in 256 color modes, but not in 1024x768x16 VESA mode 104h, since the incorrect scanline value is also returned. However, the S3 also supports 800x600x16, 1024x768x16 and 1280x1024x16 accelerated video modes (20xh mode numbers). These video modes are in a packed 16 color mode, where two pixels are packed into a single byte. These modes are not supported directly by this test kit, but could be supported by a special S3 video driver (using the accelerator). Thus the only S3 video modes supported directly by these test programs are the VESA 10xh video modes (which are not accelerated). Also I have noticed that setting up the 20xh modes on S3's stuffs up the video palette, but using the VESA 10xh numbers doesn't. Another problem that I found was that the 86c911 chip seems to have trouble doing page flipping in the 1024x768x16 video mode (VESA mode number 102h, not S3 mode number 202h). This problem is non-existant on the 86c924.
