VGACAP v7.2 Copyright 1987-91 Lawrence & Marvin Gozum, MD.

VGACAP captures MCGA/VGA 320x200x256 or SVGA 640x480x256 and 800x600x256
screens.  VGACAP72.ZIP includes VGAFIL to convert 256-color 320x200,
640x480, or 800x600 grabs to GIF, PCX, BMP (Windows 3.0) and TGA (Targa 16),
as well as hardcode VGACAP for FAST, SVGA SCREEN GRABS.

You can also view VGACAP and VGAFIL as a generic conversion utility since
almost any MCGA/VGA/SVGA image from (320x200 to 800x600) that can be viewed,
can be converted to GIF, PCX, BMP or TGA format !

Update v7.2     * FAST VGA 640x480x16 grabs

		  - Automatically detects VGA 640x480x16 mode and
		    jumps to appropriate routine.

		  - Works in BIOS or ANY SVGA hardcoded setting.

		* 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.

		* BUGFIX: Trident 8800/8900 and Zymos routines for fast
		  SVGA grabs were flawed; corrected.


Update v7.1     * BUGFIX: GVGA code was "misplaced"; corrected.

                * BUGFIX: Tseng 4000 was in write bank only; this has been
                  modified for READ and WRITE bank operations.

                * VGAFIL (v2.1) - adds "-C" to configuration option to
                  maintain common interface with MVGAVU and other utils
                  we will release.

Update v7.0     * VGAFIL (v2.0) now supports Targa 16 (uncompressed TGA)
                  format for those who want to edit/modify SVGA screen grabs
                  with XGA, Hercules Graphics Station, Targa and other cards
                  that support 32KB, 64KB, or 1.6MB colors !

                * BUGFIX: When VGAFIL was used in COMMAND LINE mode and the
                  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!>.

                * SVGA 640x480x256 and 800x600x256 hard-coded for DIRECT
                  memory/bank access; captures in about 2-3 seconds (based
                  on SX with 28 ms. hard disk).  The following SVGA chipsets
                  are supported and can be configured with VGAFIL.

                * 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.
