VGACAD SYSTEM v2.5 UPDATE
***************************
VGACAD (Main)
Update v2.5 * Ahead-B SVGA support added.
* BUGFIX: Color matching algorithm performed erratically
with similar palettes; restored original algorithm at
VDISK, IMGPRO and MAIN program modules.
* BUGFIX: SVGA Tseng 4000 bank switching routines did not
reset extensions resulting in unpredictable effects on
some Tseng 4000 cards (weird!); anyway, corrected.
* BUGFIX: Somehow ALL the Everex VRAM video setting
routines were totally deleted (!?!); corrected.
* BUGFIX: SVGA C&T 451,452,453,455,456 routines were
flawed; corrected.
* BUGFIX: Some Everex 678 with Trident modes, and Everex
VRAM with Tseng 4000 modes got mixed up; corrected.
* BUGFIX: When selecting SVGA sections for cutting/copying,
the last line on the bottom and all pixels to the right of
the rectangle were not XORed which created the illusion
of not saving those pixel when they actually were anyway;
corrected.
VGACAP v7.5-7.3 * BUGFIX: Trident SVGA bank routines were still flawed
(we tried to accomodate the rare BR version of the
TVGA chip), resulting in erroneous bank switching;
corrected by restoring the standard 64KB TVGA 8800/8900
banking code. <damn those BRs!>
* Added a new 'Trident' SVGA bank switching mode labelled
'Zymos'; this is essentially similar to Trident 8800/8900
chipset BUT with similar WRITE/READ bank switching
routines.
* BUGFIX: Video7 1024x768x16 grabs required a different
bank switching routine; added 16-color bank switching code.
* BUGFIX: C&T 452/453 1024x768x16 grabs required a different
bank switching routine; added 16-color bank switching code.
* Added FAST SVGA 1024x768x256 capture funtionality.
* Added FAST SVGA 1024x768x16 capture funtionality.
* Added FAST SVGA 800x600x16 capture funtionality.
* BUGFIX: SVGA C&T 452 and 453 bank routines were flawed;
corrected.
* BUGFIX: When VGACAP is loaded and one or more files are
saved, subsequent reloading of VGACAP would be accepted
(ie., two or more VGACAP resident files would be
permitted); corrected.
* Added Ahead-B chipset support (VGA Wizard).
VGAFIL v2.5-2.3 * MAJOR BUGFIX: Some combinations of DOS and environment
variables resulted in "0" lenght PCX, BMP and TGA files
(something to do with too many or conflicting DOS file
handles); corrected!
* FASTER PCX encoding.
* Avoids sign-on screen if REGISTER.OVL is detected and
verified; saves you a keystroke.
* Customization menu updated to accomodate 'Zymos' setting.
VGACAD SYSTEM v2.4 UPDATE
**************************
VGACAD (Main)
Update v2.4 * BUGFIX: VDISK module did not accept changed palette from
MVGAVU; corrected.
* BUGFIX: Users with minimal "low" RAM (eg, 32KB free RAM
after runnign VGACAD) "hung" when chaining to GIFHEX or
GIFPUB at the VDISK Module. Corrected; most RAM buffers
used by VDISK are now deallocated prior to chaining to
any "chainable utility" via VDISK.
* BUGFIX: LARGE hard disks users (>32Meg) or users with
hardware 'hard disk caching devices' experienced SEVERE
problems with IMGPRO functions involving the saving or
loading of image data. This caused the infamamous
"ERROR 5 at VDISK" or "blank"/"trashed" screens saved
to TEMP files.
The "/SL:" option now triggers direct disk/video RAM to
go through slower but safer LOW memory buffers to avoid
"mix-ups" with hardware caching techniques.
To trigger "cache-compatible" routines, ALWAYS use the
"/SL:" option:
eg.; VGACAD /SL:1
* BUGFIX: Trace/Fill function would 'hang' if the "seed"
point had less than x 2x2 pixel clearance; corrected.
* BUGFIX: EXTCHAIN did not detect and verify REGISTER.OVL
file; corrected.
VGAFIL v2.2 * Adds "-H" option for "hex" (ie., 16-color GIF encoding.
No need to rename files to NYBLSCRN.* anymore; now you
encode as many as you want in one sitting without getting
out of VGAFIL.
VGACAP v7.2 * FAST VGA 640x480x16 grabs
- Automatically detects VGA 640x480x16 mode and
jumps to appropriate routine.
- Works in BIOS or ANY SVGA hardcoded setting.
* BUGFIX: Trident 8800/8900 and Zymos routines for fast
SVGA grabs were flawed; corrected.
VGACAD SYSTEM v2.30 UPDATE
**************************
VGACAD (Main)
Update v2.30 * Total overhaul of IMGPRO module. Mode selection now
follows MVGAVU (v3.0 and up) user interface. Summary of
SVGA chipset support of IMGPRO module.

RAW files were not located in the default directory or
drive, "0 x 0" images were encoded and subsequent system
"hang" resulted. This has been corrected <whew!>.
* Adds "-C" to configuration option to maintain common
interface with MVGAVU and other utils we will release.
* Supports Targa 16 (uncompressed TGA) format for those who
want to edit/modify SVGA screen grabs with XGA, Hercules

Oak --------------- (no examples)
BIOS -------------- (100% BIOS pixel read & palette usage)
* Custom Western Digital PVGA (Paradise) support for WD90C01,
WD90C10 and WD90C11 chipsets; forces single bank select
just in case you capture while viewing with a program that
uses the dual bank switching mode or new 800x600x256 mode
supported by WD90C11 chip.
* Genoa GVGA 6100, 6200, 6300, 6400, 6600 chipset support.
These cards are radically different from the 5x00 series.
* Headlands/V7VGA4 (Video7 Version 5 chipset) support added
for those with Video7 1024i SVGA cards (or clones, if any).
* Video7/V7VGA (Version 1 to 4) chipset support modified for
increased compatibility, read/write operations and speed.
* New Trident TVGA 8800/8900 chipset support. Forces 64KB
bank switching mode and adjusts for the weird bank
numbering scheme. Customized for read bank operations.
* Optional Zymos/Trident TVGA 8900 chipset support using a
linear/normalized 64KB bank switching scheme (just in case
some chipsets fix/normalize the weird bank numbering
scheme). Customized for read bank operations.
* New Chips & Technologies support for 452/453 versions.
* BUGFIX: Tseng 4000 was in write bank only; this has been
modified for READ and WRITE bank operations.
VGACAD SYSTEM v2.20 UPDATE
**************************
VGACAD (Main)
Update v2.20 * BUGFIX: Some 386 DXs were having problems saving and
loading BLoaD screens directly to or from video RAM
(probably some memory cache method ?); all routines in
VGACAD using this approach have been changed.
* BUGFIX: Some OEM SVGA/VGA cards were having PALETTE read
and write problems (despite register-compatibility claims);
this is now avoided by BIOS routines being the DEFAULT.
Users opting to use FAST direct hardware palette read/write
can do so using the "/P" option.
* BUGFIX: After viewing a virtual screen section and
subsequently decoding a new image the virtual screen
section was "matched" with the worng palette; this
has been corrected.
* BUGFIX: Saving ANY virtual image smaller than 640x400
resulted in a corrupted image; this has been corrected.
* "/R" command line option is now the default. If you
specify the "/R" option, VGACAD will reserve an additional
64KB of RAM to speed-up certain functions.
VGAFIL v1.3 * BUGFIX: Some OEM SVGA/VGA cards were having PALETTE read
and write problems (despite register-compatibility claims);
Palette read/write functions now follow whatever setting
(Slow BIOS or FAST hardware access) has been triggered
with VGACAD.
VGACAD SYSTEM v2.10 UPDATE
**************************
VGACAD (Main)
Update v2.10 * BMP (Windows 3.0 file format) 256-color support
- BMP virtual screen loading/importing (to 32KBx32KBx256).
- BMP conversion/encoding/exporting (to 2048x2048x256).
- Automatic 1:1 aspect ratio correction.
* Transparent cut & paste ("lasso" effect) added to full-
screen SVGA/MVGA image processing.
When using the SVGA/MVGA iPut ("paste") function, pressing
BOTH mouse buttons instead of simply pressing the LEFT
mouse button will paste the image with a transparent
background. THIS NEW FUNCTION DOES NOT MATCH COLOR
PALETTES. USE ONLY "CLIPS" THAT HAVE BEEN COLOR MATCHED.
* ZOOM ERASE MODE - Selecting COLOR 0 in Zoom Mode is
now allowed. It can be selected from the colorbars
or from the color map. This is particularly important in
maximizing use of the SVGA/MVGA transparent cut & paste
function.
* Enhanced SVGA/MVGA rectangle definition routine.
* Fast SVGA full-screen update/save/load/undo when SVGA
video mode matches the virtual screen dimensions in the
following "standard" SVGA modes.
- 640x400x256
- 640x480x256
- 800x600x256
* BUGFIX: When decompressing PCX SVGA images, the
destination virtual disk was not checked for adequate
disk space. This has been corrected.
VGAFIL
Update v1.2 * BMP (Windows 3.0 file format) 256-color support
VGACAP
Update v6.1 * 100% BIOS-compatible function for palette access has
been restored (ie., same as VGACAP v5.0 or v4.0) when
slower but safer BIOS configuration is selected.
