Installation Instructions
S3 86C801/805/805i/928/928PCI OS/2 Beta Drivers

Date:	11/30/93

Installation Considerations

1.	The installation process assumes that the user knows the  
	maximum vertical refresh rate as well as the maximum 
	resolution of the monitor.

2.	When installing the S3 driver over a non-S3 driver 
	(e.g., SVGA), the standard IBM VGA driver must be 
	installed first.  This is not required if an S3 driver is 
	already installed.

3.	The driver diskette must be labeled "S3 DRVS".  If it is 
	not labeled installation will fail.

4.	The S3 driver will not install unless an S3 chip-based 
	card is installed in the machine at the time of driver 
	installation. 
  
5.	This driver is for the S3 86C80X/928 chips with an AT&T
	491-compatible RAMDAC and the 86C928 with a Brooktree 
	BT485 RAMDAC.

6.	The 86C928 with Brooktree Bt485 RAMDAC does not support 
	the 1280x1024x256 color resolution.

7.	S3 cards with GENDAC I or II are not supported.
