*****************************
*  INSTALLING OS/2 DRIVERS  *
*****************************

This set of drivers work for OS/2 2.1, 2.11, and OS/2 Warp.

   
BEFORE YOU BEGIN
----------------

1. You need to know the maximum horizontal scan rate for your monitor. 
   You'll need this information to set up SETCRT to deliver the best 
   possible vertical refresh rates from your monitor.


2. OS/2 must be installed and running on your system using the STANDARD VGA
   driver supplied by IBM.  Do not attempt to install the Graphite Terminator
   software over any other driver!


3. If you are creating the installation diskettes yourself -- which you would 
   be doing if you had downloaded the drivers from one of our electronic
   services -- you must make sure the diskettes have the following volume
   labels:

   "S3 DRV1" for Disk #1
   "S3 DRV2" for Disk #2

   (Note: do not type the quotes [""] around the volume labels!  They are 
   used here for clarity only)


4. Make sure that all applications, including any DOS or Win-OS/2 sessions,
   are closed BEFORE begining the installation.
 

  
INSTALLING THE DRIVERS   
----------------------
 
1. Open an OS/2 command prompt (either Windowed or full screen). 

 
2. Insert the "Supplemental Display Driver Diskette 1" into the floppy drive. 


3. Change to that floppy drive. 


4. Assuming you're installing from floppy drive A: and OS/2 is installed on
   fixed disk drive C:, type the following:

   INSTALL A: C: [Enter]

   If you are installing from another drive or to another drive, just
   substitute the appropriate drive letters.


5. After a number of files are copied, you'll be prompted to insert the
   "Supplemental Display Driver Diskette 2."  Insert the diskette and
   press [Enter] to continue.  Once the installation is complete, remove
   the floppy disk and exit the OS/2 session.
