- The Universal VESA TSR
- ----------------------

-
- What is it?
- -----------
-
- The Universal VESA TSR is a small Terminate and Stay Resident (TSR) program
- that provides extends the Video BIOS routines of SuperVGA video cards
- to make them compatible with the Video Electonics Standards Association
- (VESA) recommended extensions.
-
- By having a video card that has a VESA compatible BIOS, or by installing
- this small TSR, programs that support the VESA programming interface
- will work correctly for your SuperVGA. This helps to solve a lot of
- problems with compatability between different SuperVGA cards on the
- market.
-
- Why use it?
- -----------
-
- You may already have a VESA TSR for you video card, or you video card
- may have a VESA compatible BIOS already, so why would you want to use
- this program?
-
- The simple answer is that most of the TSR's that exist today, and a lot
- of the not-so-new SuperVGA cards that are around implement an older version
- of the VESA programming interface (if any at all). For this reason, some
- programs that use the advanced features of the new VESA standard will
- not work with the TSR or BIOS that you currently have.
-
- So what advanced features does this TSR provide that other's don't? The
- Universal VESA TSR implements the VESA Version 1.2 programming interface,
- which supports the following features:
-
- - VESA page flipping. High performance animation programs can
- use your card to full potential using the VESA BIOS to implement
- extended page flipping (imagine, 1024x768x16 double buffered
- animation, or even 800x600x256 and 640x400x32k on a 1Mb video
- card!!).
-
- - Support for the 32k and 16 million color video modes. As well
- as supporting the industry standard 16 and 256 color video
- modes.
-
- Hardware Requirements
- ---------------------
-
- The Universal VESA TSR contains '386 dependant code, so it will only
- run on machine that have and 80386 or better CPU. Currently the
- Universal VESA TSR supports the following SuperVGA chipsets (note that
- not all of these have been fully tested):
-
- - 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
- - S3 86c911/924/801/806/928
- - Advance Logic AL2101 SuperVGA
- - MXIC 86010 SuperVGA
- - Primus 2000 SuperVGA
- - RealTek 3106 SuperVGA
- - Cirrus CL-GD 5422 SuperVGA
-
- The Universal VESA TSR seems to have problems with QEMM, since QEMM does
- something weird with the Video BIOS. In order to fix this problem,
- you should use the QEMM 'exclude' options to exclude the Video BIOS
- area. Do this by including the following in the QEMM options:
-
- EXCLUDE=C000-C1FF
-
- How do I install it?
- --------------------
-
- You can install the TSR from the command line, or from your autoexec.bat
- file. Don't worry about installing it twice, it will automatically detect
- if you have already installed it.
-
- To install it simply type:
-
- univesa
-
- from the command line. It will determine what type of SuperVGA card you
- have installed and install itself accordingly.
-
- When installed the Universal VESA TSR takes up approximately 7k of memory.
- All of the code required to detect the video adapter and available video
- modes is removed after the program is installed, saving on the amount
- of memory required. You may also load the TSR high.
-
- Can I get the source code?
- --------------------------
-
- Yes, the full source code for this library is available, along with a
- number of test programs (with source) for programming SuperVGA cards
- in a device independant manner in a SuperVGA Test Kit Library. You can
- probably download this from Simtel-20 or garbo (or one of it's mirrors)
- or you can ftp the absolute latest version from:
-
- godzilla.cgl.rmit.oz.au: kjb/MGL/svgakt??.zip
-
- How can I contact the Author?

- you have any questions you would like asked, feel free to contact me
- through one of the following methods.
