Automatic installation:
	1. Go to disk drive that has Cadkey or Datacad.
	   Don't worry, it will figure out which is present.
	2. Place the driver install disk in drive A:.
	3. Type "A:INSTALL" <cr>.
	4. Run CONFIG program when prompted, selecting this driver.

Manual installation (Cadkey)
	1. Go to disk drive that has Cadkey.
	2. Place the driver install disk in drive A:.
	3. Change to the "\CADKEY" directory.
	4. Copy "A:\CK_AGX.EXE" to the current directory.
	5. Rename the file "GRDEV.DAT" to "GRDEV.BAK".
	6. Enter the following command:
	   "COPY GRDEV.BAK+A:\GRDEV.DAT GRDEV.DAT" <cr>
	7. Run CONFIG program, making the following selections:
	7.a Select "Set graphics options".
	7.b Select "Select graphics device" option.
	7.c Select "XTEC AGX".
	7.d Select the appropriate resolution option, depending upon the
	    monitor you have.
	7.e Select the rest of the graphics options, depending upon 
	    personal preference.
	7.f Exit, saving the new configuration.

Manual installation (DataCAD)
	1. Go to disk drive that has Datacad.
	2. Place the driver install disk in drive A:.
	3. Change to the "\MTEC\DRV" directory.
	4. Copy "A:\CK_AGX.EXE" to the current directory.
	5. Rename the file "DRIVERS.GD2" to "DRIVERS2.BAK".
	6. Enter the following command:
	   "COPY GRAPHICS2.BAK+A:\DRIVERS.GD2 GRAPHICS.GD2" <cr>
	7. Change to the "\MTEC" directory.
	8. Run CONFIG program, selecting the "XTEC AGX" driver.

Driver Un-Install (Cadkey)
	1. Change to the "\CADKEY" directory.
	2. Enter the following command.
	   "COPY GRDEV.BAK GRDEV.DAT" <cr>
	3. Delete the file "CK_911.EXE"
	4. Run the Config program, selecting a new device driver.

Driver Un-Install (DataCAD)
	1. Change to the "\MTEC\DRV" directory.
	2. Enter the following commands:
	   "COPY DRIVERS2.BAK DRIVERS.GD2" <cr>
	   "COPY DRIVERS4.BAK DRIVERS.GD4" <cr>
	3. Delete the file "CK_AGX.EXE".
	4. Change to the "\MTEC" directory.
	5. Run the CONFIG program, selecting a new video driver.



		D R I V E R   U S E
		-------------------

The driver is a TSR (Terminate and Stay Resident) driver that must be
invoked before Cadkey (or Datacad) will run. The driver will accept
certain command line options that will change the behaviour of the
driver. These options will allow you to: remove a previous copy of the
driver from memory, or to install the driver at a different interupt.

To remove a previous copy of the driver, use the '-r' option.

This driver will install itself on interupt 60h by default. To install
it at some other interupt, use the '-f##' option. Where '##' is
replaced by a number between 60 and 67.

Examples:
 'ck_agx'	will install the driver at interupt 60h
 'ck_agx -f62'	will install the driver at interupt 62h
 'ck_agx -r'	will remove the last installation of the driver.



		T R O U B L E S H O O T I N G
		-----------------------------

Driver won't install in memory.

	Couldn't find an AGX based board

		Install graphics card, and re-run device driver.

	No interupt vector may be open.

		The driver scans all the interupt vectors between 60h
		and 67h before installing itself. It all of these
		appear to be in use, the driver will not install. Try
		forcing the driver to each vector, until one is found
		that won't hang your machine.

High loading

	To conserve DOS memory, this driver may be loaded into high memory.
	This can be accomplished by using a 386 memory manager such as QEMM or
	386max. 

	QEMM Example:
	"c:\qemm\loadhi c:\cadkey\ck_agx"

	386MAX Example:
	"c:\386max\386load envfree prog=c:\cadkey\ck_agx"


Unloading high loaded drivers

	QEMM Example:
	"c:\qemm\loadhi /nope c:\cadkey\ck_agx -r"

	386MAX Example:
	"c:\386max\386load quiet prog=c:\cadkey\ck_agx -r"
