    VRTXsa driver support package for RG-7XX and RG-79XX graphics boards
    =====================================================================

This package consists of:

 1. This README file

 2. demo directory
 2a. rginit79.c - demo program to initialize the graphics board device
 2b. rginit79k.c - demo program to initialize the graphics board device with
		  the keyboard and mouse enabled
 2c. gdemo.c - demo program for testing the rg-7900
 2d. ptype.h - header file for demo program
 2e. Makefile - makefile for building demo program
 2f. demo.script - xsh script to build and load os, load and run demo

 3. lib directory
 3a.  lib/rg.lib - Microtec VRTXsa library archive for the C Graphics Library

 4. include directory
 4a.  raster/*.h - include files to use when building application programs
 4b.  raster/drv/device.h - include file for driver and device initialization

 5. driver directory
 5a.  driver/rg7drv.o - Microtec VRTXsa driver for RG-7900 graphics board
 5b.  driver/rgidev.def - xconfig definition file to build VRTXsa with the
			  rgi driver included and to set initialization
			  entry points.


Notes:
=====
1. The library and driver are precompiled in Microtec IEEE format for
   Spectra VRTXsa version 3.1.2. They will not work with VRTX32.

2. The library and driver also require the rtnofp.lib (in addition to
   the standard libraries included with the OS). They do not use any
   floating point, nor do they require any IFX library routines.

3. The library currently interacts with the driver via direct calls.
   This means any graphics application tasks must run in supervisor
   mode.
