- VGACAP v7.7 Copyright 1987-91 Lawrence & Marvin Gozum, MD.
-
- VGACAP captures MCGA/VGA 320x200x256 or SVGA 640x480x256, 800x600x256
- and 1024x768x256 screens. VGACAP74.ZIP includes VGAFIL to convert 256-color
- 320x200, 640x480, 800x600 or 1024x768 grabs to GIF, PCX, BMP (Windows 3.0)
- and TGA (Targa 16), as well as hardcode VGACAP for FAST, SVGA SCREEN GRABS.
-
- VGACAP now supports fast VGA/SVGA captures for 640x480x16, 800x600x16
- and 1024x768x16 !!!
-
- You can also view VGACAP and VGAFIL as a generic conversion utility since
- almost any MCGA/VGA/SVGA image from (320x200 to 1024x768) that can be
- viewed, can be converted to GIF, PCX, BMP or TGA format !

- Update v7.7 * BUGFIX: Total overhaul of 1024x768x256 grab routines.
-
- * BUGFIX: Trident bank switching code modified to force
- 64KB paging with single page mapping.
-
- * VGAFIL v2.7 now encodes BMP files via a special color
- reduction and remapping routine to virtually eliminate
- "hotspots" when BMP images are remapped by Windows 3.x;
- resulting in FASTER LOADS too !
-
- * VGAFIL v2.7 cosmetic overhaul (similar to MVGAVU).
-
- * VGAFIL v2.7 now incorporates faster PCX encoding.
-
- * VGAFIL v2.7 BUGFIX: missing right column of pixels with odd
- image PCX sizes; corrected.
-
- * VGAFIL (v2.7) BUGFIX: "0" lenght PCX, BMP and TGA files
- did not trigger the right error code (ie., unsupported
- image dimensions); corrected.
-
-
- Update v7.6 * BUGFIX: C&T 1024x768x16 and 1024x768x256 bank switching
- code code got exchanged, thereby messing up each other;
- corrected.
-
- * BUGFIX: Video7 1024x768x16 and 1024x768x256 bank switching
- code code got exchanged, thereby messing up each other;
- corrected.
-
- Update v7.5 * 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.
-
- * VGAFIL (v2.5) customization menu updated to accomodate
- 'Zymos' setting.
-
- * 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.
-
-
- Update v7.4 * 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.
-
- * VGAFIL (v2.4) now avoids sign-on screen if REGISTER.OVL
- is detected and verified; saves you a keystroke.
-
- Update v7.3 * 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 (v2.3) 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!
-
- * VGAFIL (v2.3) FASTER PCX encoding.
-
- 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.
