- Log of changes for the SuperVGA Test Library
- --------------------------------------------
-
- Version 3.1 (7 March 1993)
-
- - Changed the Universal VESA TSR to compile in the large memory model,
- and to startup in C to perform the SuperVGA detection etc. Thus it
- now also takes command line arguments to force it to work with any
- SuperVGA configuration. It can now also be compiled in testing mode
- where it will call a C testing procedure after installing the interrupt
- handlers so it can be debugged easily using Turbo Debugger. It will
- not go TSR when in testing mode, but simply restore the interrupt
- vectors and quit.
-
- - Added support for returning optional mode information to the
- Universal VESA TSR to make it more compatible.
-
- - Fixed bugs in the detection of TrueColor video DAC's.
-
- - Change the version numbering for the Universal VESA TSR to match
- the SuperVGA test kit library.
-
- - Added command line options to the programs to allow the
- programs to be forced to run for a particular video card. This
- includes the Universal VESA TSR.
-
- - Added code to both the test programs and Univesal VESA TSR to
- check the type of CPU before running the program.
-
- - Fixed problems with clearing unavailable 24 bit video modes for
- Genoa 7900 and Speedstar 24 cards. This should work now.
-
- - Added code to detect whether the 1280x1024x16 color video mode
- is available on ET4000 cards (older ones don't have it).
-
- - Fixed problem with detecting 32k and 16m color support on Everex
- Viewpoint TC card. Also fixed problem with not correctly calculating
- the number of pages on Everex boards.
-
- - Fixed problem with detecting the number of pages on Cirrus 5422
- boards.
-
- - Attempted to fix problem with extended flipping of Standard VGA
- modes on Ahead SuperVGA's.
-
- Version 3.0 (30 Feb 1993)
-
- - Added the Universal VESA TSR. This will provide full VESA 1.2 BIOS
- functionality for all supported SuperVGA's.
-
- - Restructured the test kit code into test programs and an underlying
- 'C' callable library for each video mode type (16, 256, 32k and
- 16m colors). Thus you can now easily use the library code in your
- own programs.
-
- - Fixed bugs with the Paradise WD90C30 video card.
-
- - Add a number of hacks to the ET4000 code to make it work with all the
- different 24 bit cards that have different mode numbers (MegaEva/2,
- Diamond Speedstar 24, Genoa 7900).
-
- Version 2.1 (24 Feb 1993)
-
- - The library is now '386 specific, given the incredibly cheap
- price of '386 hardware (and the benefits obtained).
-
- - Added support for all the standard EGA and VGA modes as well, so
- you can test page flipping etc for all possible video modes.
-
- - Better support for calculating the number of available pages, so
- will work out correct number of pages for adpaters with > 1Mb on
- board.
-
- - Add support to determine the number of available pages for a
- video mode during video adapter detection.
-
- - Restructured the entire library to help in the development of the
- Universal VESA TSR program. The framework has now been laid for
- this project to progress.
-
- - Added detection of available video pages for a specific mode
- before the mode is actually set.
-
- - Removed memcheck from VESA detection routine. This does not seem to
- work correctly on all VESA boards. If the VESA BIOS gives incorrect
- memory values by not restricting video modes depending on the available
- memory, we can do nothing about it.
-
- - Fixed up S3 support to only use the VESA 10xh video modes, and not the
- 20xh co-processed video modes, to ensure compatibility.
-
- - Removed all support for the S3 1280x1024x16 color video mode. This
- is such a silly mode that it is not worth supporting...
-
- - Fixed bugs in a number of video adapter routines.
-
- Version 2.0 (28 Nov 1992)
-
- - Modified code to be '286 processor dependant, for extra speed.
- Who uses XT's for real Graphics anyway?
-
- - Fixed bug in Trident 8900 page flipping code.
-
- - Fixed bug in Paradise initialisation testing code.
-
- - Fixed bug in numbering of VESA 32k video modes.
-
- - Added a number of modules and include files to define the video
- mode numbers supported by each particular video card.
-
- - Added tables of symbolic video mode and driver names.
-
- - Restructured the test programs to work with any of the supported
- video modes, and to provide more useful information about whether
- the test has succeeded or not.
-
- - Added both 32k color and 16 million color test programs.
-
- - Modified the mode setting code to remember if the EGA/VGA 43 line
- mode was set, and to reset it when graphics mode is exited if it
- was.
-
- - Removed old write bank setting routines. Now you simply call
- [NewBank] to set both the read/write banks, and [ReadBank] to
- change the read bank to some other value.
-
- - Added support for VESA SuperVGA extended page flipping!
-
- - Detection of VESA SuperVGA's can be done either before or after
- detection of all supported SuperVGA's.
-
- - Added support for separate read/write banks and extended page
- flipping for more boards.
-
- - Added support for more SuperVGA's (AL2101, MXIC, Primus 2000,
- RealTek 3106).
-
- - Improved SuperVGA detection code by making the tests for each
- video card a lot more stringent, to avoid misidentifications. Also
- each routine will modify the list of available modes depending
- on the installed chip version.
-
- - Added support for detecting the type of Video DAC installed, for
- both HiColor (15 bit) and TrueColor (24 bit) type DAC's.
-
- - Added support for wierd boards like the S3, which have large
- bytes per line values.
-
- - Added support for the Oak Tech OTI-037C SuperVGA (only has
- 800x600x16 color mode tho).
-
- - Fixed a number of bugs in the Trident 8900 code. Should work well now.
-
- Version 1.1 (19 Nov 92)
-
- - Added memory detect routine for VESA compatible SuperVGA's.
-
- - Saving the BytesPerLine value for VESA compatible SuperVGA's, and
- better handling of VESA Video Mode numbers in MGL_detectGraph().
-
- - Support for VESA 1.2 video modes (up to 1280x1024 16 million colors)
-
- - Added support for AcuMos SuperVGA detection and bank switching
-
- - Added support for S3 based SuperVGA's bank switching (missing
- from previous release) and extended page flipping. Also added
- checking for S3 HiColor video mode availability.
-
- - Added support for detection of newer ATI SuperVGA chips that
- support up to 1M of video ram.
-
- - Fixed bug in bank switching code for Video7 V7VGA Version 5
- chipsets (I think this is what the Video7 1024i has).
-
- - Added code to differentiate between C&T 82C451/452/453 chips
- as bank switching is different for each chip.
-
- - Fixed bug in Tseng ET3000 bank switching code causing it not to
- work in 256 color modes.
-
- - Added enhanced memory size detection for Everex video boards
-
- - Added support for separate read/write banks and extended page
- flipping for Ahead B SuperVGA's
-
- - Modified to check for HiColor DAC internally in MGL_detectGraph,
- adjusting the list of available modes accordingly. Thus we no
- longer have the grSVGA_ET4000HC et al device numbers.
-
- Version 1.0 - First public release (14 Nov 92)
