This driver includes 16 and 24 bpp resolutions obtain from 
IBM S3 32 Bit driver.  See IBM's release note, "README.IBM", for 
resolutions and boards supported.  This release note also includes
software limitation with the 16 and 24 bpp resolutions.  


FUNCTIONAL RESTRICTIONS: 

This driver does not support the following functions:

1)	Read the "README.IBM" file for limitations with the 16
	and 24 bpp modes.

2)	Software Motion Video may require an aperture address 
	setting on local bus systems.  If video playback is 
	distorted or displays in the wrong location, add the 
	following line to the CONFIG.SYS file:

		SET VIDEO_APERTURE=xx

	where "xx" is the actual aperture address.

	Contact the system manufacture for the address.

3)	In the 1280x1024x256 resolution, opening a window or
	moving a desktop object will display horizontal lines that
	disrupts the desktop image. This is a bandwidth limitation
	on 801 and 805 adapters with MClock set to 50Mhz.
	Increasing the MClock to 55Mhz will resolve this problem.  


	Refer to the board documentation or contact the board
	manufacture for instructions on how to do this.


3)	Windows Word 2.0 & Excel 4.0:	Switching back and forth 
					between Word and Excel  
					may cause a General 
					Protection Fault in Word.

4)	Windows Tetris:	"Help" pop-up menu leaves shifted pixels  
			in the upper left of the game area.

5)	Describe 4.0:	Using gray background in Describe 4.0
			leaves horizontal lines when scrolling
			document.  This also happens with IBM
			8514/a 32 bit driver and card.

6)	Windows Paintbrush: 	Shaded background area does not 
				get restored after pulling down a 
				menu and clicking anywhere in the 
				document area.	This also happens 
				with IBM 8514/a 32 bit driver and 
				card.

7)	Windows Recorder:	Switching to Win-OS/2 full screen 
				which is running Windows Macro 
				Recorder with Character Map 
				displays a black screen with a 
				white arrow cursor. Win-OS/2 full
				screen can be restored by closing
				the Win-OS/2 full screen session
				from the PM Desktop and then
				opening a new session.

SUPPORTED HARDWARE:	

These drivers have been tested on a limited set of IBM* Personal
Computer compatible systems and add-in graphics adapters.  Many 
others should also function correctly.  The following systems and 
adapters have been used to verify the functionality of the drivers.

1)	Actix** Graphics Engine 32 Series Adapters
2)	Premier Metheus** Adapter
3)	IBM Valuepoint* System
4)	DECpc** 433DX/LP System
5)	ALR** System
6)	Gateway** 2000 4DX-33V System
7)	HP** Vectra 486/33U System
8)	Opti** Chipset 	 
9)	SIS** Chipset 
10)	AIR** Chipset
11)	Intel PCI 486 Saturn** Chipset 

Many popular add-in graphics adapter companies such as Diamond 
Computer Systems, Number Nine, Orchid Technologies, and STB 
Systems customize certain hardware features.  For example, a 
different clock chip may be incorporated into their board design.  
Please be aware that board differences require software
customization for correct functionality.  Contact your hardware 
vendor for drivers adapted for their boards.

Support:  	Problems with this driver should be directed to
		your hardware vendor's service line or BBS.
