	The driver set consists of the following disk:

	- Display Driver Diskette 1 (volume label DISP 1)
	- Display Driver Diskette 2 (volume label DISP 2)


	INSTALLATION:
	-------------

	The OS/2 installation procedure is as follows:

	1- Under OS/2 desktop select icon: OS/2 System and then
	   icon: Command Prompts.

	2- Select DOS Window (either Desktop or FullScreen).

	3- Insert the driver diskette 1 into the floppy drive. (e.g. drive A:)

	4- Run INSTALL.BAT or INSTALL.CMD.  (e.g. if the floppy drive
	   is A: and OS/2 is installed on C: then type "A:\install a c")
	   For help on INSTALL.BAT, just type "A:\install".
	   This will load necessary files needed for OS/2 installation on
	   the hard disk.
	   Steps 1-4 are required only for the first time installation of
	   Avance Logic drivers. On subsequent installation of drivers
	   you may skip the steps 1-4.

	5- On OS/2 window (under Command Prompt) type DSPINSTL C.

	6- Select "Primary Display" and click on "OK".

	7- Select "Avance Logic, Inc." in the driver selection menu.

	8- Select "Install Using Defaults for Monitor Type" in the
	   menu "Monitor Configuration/Selection Utility".

	9- User will be prompted for Video Refresh Rate Selection Menu.
	   If you are not sure about the monitor, select "NO". Selecting
	   wrong refresh rate not supported by monitor could hang OS/2
	   system and you may be required to load the OS/2 system all
	   over again.  If you select "YES", utility: AScanOS2 is invoked
	   which will present the available scan rates.  If you are still
	   not sure about which scan rates to choose, select the lowest
	   scan rates in each of the four columns.  For information on
	   AScanOS2 read Help provided in the program.

       10- Select desired display resolution.

       11- Use Disks: Display Driver Diskettes 1 and 2 when prompted.



	NOTE:
	-----

	- Please note the volume label of "Display Driver Diskettes" are
	  "DISP 1" and "DISP 2", respectively.  If you make copies of these
	  disks, make sure you give correct volume labels.  (Use
	  DOS command "LABEL" to change the volume label of a disk.)

	- To change resolution of the installed drivers or to change
	  the refresh rate of the video screen, it is necessary to
	  perform the installation steps 5-11 as stated above.

	-You may encounter some warning messages during the installtion,
	 please ignore them and press OK button.

	DE-INSTALLING DISPLAY DRIVERS:
	------------------------------

	- It is important to note that you must de-install Avance Logic, Inc.
	  drivers and load SVGA (Super VGA) drivers before you change the
	  video board on the system.  To change to SVGA drivers follow the
	  following steps.

	- If you want to remove Avance Logic, Inc. display drivers,
	  follow steps 5-11 and select "Super VGA (SVGA)" instead of
	  "Avance Logic, Inc." when prompted at step 7.  Use IBM's OS/2
	  original disks during this installation.  During this
	  installation you may get a message saying "... File BVHSVGA
	  is newer than source file ...".  Press O.K. to this dialogue
	  box.  It is not necessary to perform shutdown at this point.

	  Open either DOS or OS/2 window.  Insert Avance Logic's driver
	  diskette 1 in the floppy drive and run "DEINSTAL".  For instance,
	  if OS/2 has been installed on drive C then type: "A:\deinstal c".
	  This will restore the original files changed during installation
	  of Avance Logic drivers.  For help on "DEINSTAL" just type
	  "A:\deinstal".

	  Perform system shutdown now, for the changes to take effect.

	  Please note that if your copy of OS/2 is on CD-ROM, make copies
	  of "Display Driver Diskettes" from CD-ROM to floppy disks before
	  you perform the de-installation steps as you need the said disks.
	  Check OS/2 user manual for instructions as to how to make copies
	  of OS/2 diskettes from CD-ROM to floppy disks.
