This is the official release version of VGADOC3, the most comprehensive
collection on (Super)VGA and other video adapter programming available.


This is a collection of programming information on (Super)VGA chipsets,
not an introduction to video/graphics programming.

The major changes from version 2 are:
Hualon, UMC, Weitek, PCVideo and Targa coverage is new.
The material on Cirrus, Compaq and XGA is vastly expanded.
The cards, clocks, history and q&a files are new.
The coverage of Hardware Cursor, BitBLT, Line Draw and Read/Write
banks in WHATVGA is new
The coverage of Hi/Truecolor RAMDACs is greatly expanded.

supervga.pas The chip specific parts: Bank switching, Mode setting,
Scrolling, Hardware Cursor, BitBLT and Line Draw rutines

whatvga.pas The menues and tests.

whatvga.doc Documentation for WHATVGA. Includes list of tested chipsets.

whatvga.chg History list of WHATVGA changes



showtest.pas Pascal source for showtest.exe

Table.pas Pascal source for table.exe

vesalie.as Assembler source (a86) for vesalie.com



Executables and data files:

chips.lst List of chipsets

whatvga.lst List of video modes

whatvga.exe The WHATVGA test program. Identifies and tests the
VGA chipset, ramdac etc. See WHATVGA.DOC for details.

showtest.exe Analyses WHVGAxx.TST files generated by WHATVGA /a

vesalie.com Modifies the VESA driver information.



Programs & source files:

All source is in pascal (except VESALIE.as).
The source files can be compiled with Turbo Pascal 5.5 or Borland
Pascal 7.0. Other versions will probably work, but ...

The assembler source (Vesalie.as) can be assembled with a86.com





I'ld be very interested in any information you may be able to supply,
whether as new information, corrections or suggestions.

Any contributors and testers will be given credit in future versions.
Please specify if you have special requests as to names or addresses
used (or not used).



While I'll try to answer all queries, experience shows that I sometimes
have trouble keeping up (I have this nasty habit of working 75 hour weeks).

Generally ongoing test sessions, new information/corrections and intelligent
queries (my decision) will get priority.
