SVGACC  A Super VGA Graphics Library For Use With MS & Borland C/C++
Copyright (c) 1993-1994 By Stephen L. Balkum and Daniel A. Sill 
*****************************************************************************

*****************************************************************************
INTRODUCTION
*****************************************************************************

	SVGACC is a Super VGA graphics library designed for use with
MS & Borland C/C++. It is written in 100% assembly language for the best
possible speed. It provides the MS & Borland C/C++ programmer with an easy
interface to the high resolution/high color video modes of the newer SVGA
video cards. Because there is no "standard" for VGA video cards above the 
320x200x256 resolution, each video card manufacturer has implemented a 
slightly different method to access these high resolution/high color video 
modes. This graphics library will automatically identify the video card and 
its installed memory. This way, the programmer may write graphics programs 
that will work on most any SVGA card without writing specific versions for 
each individual SVGA card. Over 100 subroutines and functions are provided.


*****************************************************************************
SYSTEM REQUIREMENTS
*****************************************************************************
		
	This SVGA graphics library requires a 386sx or bettor processor (to
take advantage of 32 bit instructions) as well as one of the following Super 
VGA video card brands/chip sets:
		
		Acumos SuperVGAs
		Avance Logic SuperVGAs
		ATI Technologies SuperVGAs
		Ahead SuperVGAs
		Chips and Technologies SuperVGAs
		Cirrus Logic SuperVGAs
		Everex Micro Enhancer SuperVGAs
		Genoa SuperVGAs
		Mxic SuperVGAs
		NCR SuperVGAs
		Oak Technologies SuperVGAs
		Realtek SuperVGAs
		Paradise/Western Digital SuperVGAs
		Primus SuperVGA s
		Trident SuperVGAs
		Tseng Labs SuperVGAs
		Video 7 SuperVGAs
		All VESA compatible SuperVGAs (version 1.00 and greater)

	The maximum resolution is dependent on the video card, its
installed memory, and the video monitor. Most VGA video cards support the 
320x200x256 and 640x400x256 video modes. 512k of video memory is required 
to support the 640x480x256 and 800x600x256 video modes. 1 meg of video
memory is required to support the 1024x768x256 video mode. 2 meg of video 
memory is required to support the 1280x1024x256 video mode.
	Also, video card manufactures are starting to provide VESA drivers
for their video cards. Contact the technical service department of your 
video card manufacturer and see if they have a VESA driver or updated
BIOS available for your video card.

REGISTRATION, UPGRADES, BUG REPORTS, ETC.
*****************************************************************************

REGISTRATION:
	If, after evaluating this software, you would like to register it,
the price is $35.00 for the first copy and $5 for each additional copy or
upgrade (including alternate DOS versions). With registration you will 
receive the registered version of the SVGACC graphics library and the
following bonuses:

	* Additional features such a GIF encoding, XMS support and the convex
	  polygon fill routine.
	* MS Word 2.0 Documentation (include drawings, table of contents,
	  index, ready to print).
	* A font editor (mouse/keyboard driven with source and samples)
	  that will allow you to create custom fonts (from 4x4 to 8x16)
	  as well as font object files that can be linked with your program.
	* A mouse cursor editor (mouse/keyboard driven with source and
	  samples) that will allow you to create custom mouse cursors as
	  well as mouse cursor object files that can be linked with your
	  program.
	* Limited telephone technical support (evenings only, we will be
	  glad to help you with the use of our library, but we cannot debug
	  your code.)
	* Discounts on upgrades and alternate DOS versions (such as the MS
	  QuickBasic version, the MS PDS/VBDOS version and the SP PowerBASIC
	  version.


Please see the file 'ORDER.FRM' for complete ordering information.


UPGRADES:
	We will maintain a mailing list of registered users so we may
notify you of future upgrades, discounts and products.  Should you discover
that a new version exists and we have not notified you, please contact us
for upgrade information and discounts.


COMMENTS, SUGGESTION, BUG REPORTS:
	We are very interested in what you think of our library, Please
send all comments, suggestions, ideas, and bug reports to:

	 Zephyr Software
	 P.O. Box 7704
	 Austin, Texas  78713-7704

We can also be contacted through internet:

ABOUT SHAREWARE:
	We are big believers in the shareware concept. Both of us have
purchased several shareware packages. In keeping with the concept of 
shareware, this software package is not vitally crippled, oversized,
or otherwise disabled. The only real difference between the registered 
version and the shareware version is that the registered version will 
have your name and a serial number encoded within it and you will be
permitted to distribute programs written with it.

Please help all shareware authors and register the software that you use.

Thank you for taking the time to read this.
