INSTALLING THE DIAMOND STEALTH VRAM OS/2 2.X DISPLAY DRIVERS FOR 
OS/2 FOR WINDOWS OR WARP.
	Release 1.1

Note:	You must configure the card for the appropriate monitor by setting the DIP switches on the back of the card.  This can be found in the STEALTH VRAM manual.

You must have OS2 running with the VGA driver, not the SVGA driver in order for this installation to function correctly.

I.  Installation
	1.	Select the correct files.  We suggest you make a list of the files you will need for your system configuration..

		A.  ALL CONFIGURATIONS REQUIRE EACH OF THESE FILES:

	BVHVGA.DL@
	VVGA.SY@
	VENH.SY@

	 B.  SELECT ONE OF THE FOLLOWING SETS OF FILES:

	To run the PM desktop at 1024x768 (256 colors)
	S31KX8.DL@
	SCAR1K.DR@
	S3W1K.DR@
	FONTS.FO@

	To run the PM desktop at 800x600  (256 colors)
	S3800X8.DL@
	SCAR800.DR@
	S3W800.DR@

	 C.  SELECT ONE OF THE FOLLOWING FILES:

	Note:	To make this selection you'll need to know the BIOS version of your Stealth VRAM card and the PowerUp Monitor Configuration for which your Stealth VRAM is set (see page 1:7 in the Stealth VRAM User's Manual).

	If your card is set for an IBM 8514 or NEC 2A monitor . . . AND your Stealth BIOS version is level 2 (2.XX), select 

	BVHENH20.DL@

	OTHERWISE your BIOS is level 3 (3.XX), select 
		BVHENH0.DL@

	If your card is set for a NEC 3D monitor . . . AND your Stealth BIOS version is level 2 (2.XX), select 
		BVHENH24.DL@

	OTHERWISE your BIOS is level 3 (3.XX) so, select 
		
		BVHENH4.DL@

	If your card is set for a MAG 1448 monitor . . . AND your Stealth BIOS version is level 2 (2.XX), select 
		BVHENH25.DL@

	OTHERWISE your BIOS is level 3 (3.XX) so, select 
	
		BVHENH5.DL@

	If your card is set for a NEC 4D or 5D monitor . . . AND your Stealth BIOS version is level 2 (2.XX), select 

		BVHENH28.DL@

	OTHERWISE your BIOS is level 3 (3.XX) so, select

		BVHENH8.DL@

	2.	Unpack the selected files to a temporary directory.

	A.	While running OS/2 2.x, open a windowed or full-screen OS/2 prompt and create a temporary directory (let's call it SVRAMOS2).

	B.	Make SVRAMOS2 the default directory.

	C.	Copy the files on your list of selected driver files from the distribution diskette into SVRAMOS2.

	D.	Execute the following commands from the OS/2 command prompt:

	       UNPACK *.DL@

	       UNPACK *.DR@

	       UNPACK *.SY@

	       UNPACK *.FO@

	E.	To clean up, execute the following commands:

	       DEL *.DL@

	       DEL *.DR@

	       DEL *.SY@

	       DEL *.FO@

	3.	Edit your CONFIG.SYS file.

	A.	Load your CONFIG.SYS file into the OS/2 System Editor.  You may wish to save a backup copy before you proceed.

	B.	Look for the following line:

	       	DEVINFO=SCR,VGA,[sysdrive]:\OS2\VIOTBL.DCP

	(where "[sysdrive]" is the drive on which your OS/2 systemfiles reside) and change the line to:

	       	DEVINFO=SCR,BGA,[sysdrive]:\OS2\VIOTBL.DCP

	C.	Look for the following line:

	       	SET VIO_VGA=DEVICE(BVHVGA)

	and change the line to:

	       	SET VIO_VGA=DEVICE(BVHVGA,BVHENH)

	D.	At the end of the file add the line:

	       	DEVICE=[sysdrive]:\OS2\MDOS\VENH.SYS

	(where "[sysdrive]" is the drive on which your OS/2 system files reside.  BE SURE TO OMIT THE SQUARE BRACKETS!)

	E.	Save your modified CONFIG.SYS file.

	4.	Edit your WINOS2 SYSTEM.INI file

	A.	Load your WINOS2 SYSTEM.INI file into the System Editor. (You'll find SYSTEM.INI in the \OS2\MDOS\WINOS2 directory.)

	B.	Look for the following line:

	display.drv=vga.drv

	C.	Change this line as follows:

	       If you are installing the 1024x768 driver, set:

	display.drv=s3w1k.drv

	       otherwise

		    display.drv=s3w800.drv

	D.	Save your modified SYSTEM.INI file and close the editor.

	5.	Reboot from the installation disk and copy the driver files.

	A.	Close all running applications and shut down OS/2.

	B.	Place the OS/2 2.x Installation Disk in drive A: and reboot your computer.

	C.	As the OS/2 boot proceeds, look for your first opportunity to escape to the [A:\] prompt (this will be a screen of blue text on a white background).  Press <Esc> when the screen appears and wait for the command prompt.

	D.	Play it safe:  Place the OS/2 2.x Diskette 2 in drive A: and run CHKDSK [sysdrive]: /F from the floppy.

	E.	Save the files necessary to restore your VGA configuration (just in case).  Switch to your [sysdrive]:\OS2\DLL directory, create a subdirectory called VGA, and switch to that subdirectory.

	Now execute the following commands from [sysdrive]:\OS2\DLL\VGA

	COPY ..\DISPLAY.DLL
	COPY ..\*.FON

	Note:	Saving these files will permit you to restore the PM desktop to VGA.  If you might want to restore VGA seamless Windows as well, you must also make a copy of your VVGA.SYS file (which you'll find in \OS2\MDOS) and SWINVGA.DRV (in \OS2\MDOS\WINOS2\SYSTEM).

	F.	Make your SVRAMOS2 directory the default.

	G.	Execute the following commands to copy the Stealth VRAM drivers:

	COPY *.DLL [sysdrive]:\OS2\DLL

	COPY *.SYS [sysdrive]:\OS2\MDOS

	COPY *.DRV [sysdrive]:\OS2\MDOS\WINOS2\SYSTEM

	H.	ONLY IF you have installed the 1024x768 driver set, execute the command:

	       COPY *.FON [sysdrive]:\OS2\DLL

	I.	Remove any diskette from the A: drive and reboot.  If the drivers have been copied to the correct directories and CONFIG.SYS has been correctly updated, your PM desktop should come up in the resolution you have chosen.

Known Limitations:

Warp Full Pack or Warp For Windows
The driver is unable to run in run Seamless Windows Sessions under Warp.

IV.   General information about the Stealth VRAM OS/2 2.x drivers

Under Warp:

If you have get an error:

	SYS1719:  The file [sysdrive] d:\os2\mdos\venh.sys specified in the Device statement in line [any line number] of the config.sys does not contain a valid device driver oor file system driver.  Line [line number above] ignored.  Press any key to continue...

To fix the above problem, 
	You should do a general search in the CONFIG.SYS file for the following string, "svga".  When this string occurs, delete the 's' in the "svga" string, so any string with  "svga" in it reads "vga". 

The Stealth VRAM drivers in this release are 16-bit accelerated OS/2 2.x display drivers and incorporate Seamless Windows support.  They are modelled after IBM's 16-bit drivers for the 8514A.  Therefore, that IBM's advice to users of the 8514A (in the OS/2 2.x README file) also applies to you as a user of the Stealth VRAM.  In particular, DOS VIDEO SETTINGS affect Stealth VRAM performance in Seamless and full-screen WINOS2 sessions.

You should therefore access the system menu for the WINOS2 command prompt (Click the right mouse button over the WINOS2 icon in the Command Prompts window, select OPEN and then SETTINGS from the menu, select the SESSION tab in the SETTINGS NOTEBOOK, and press the DOS (or WINOS2) SETTINGS button.  When the list box appears, scroll down to the VIDEO settings.) and turn VIDEO_SWITCH_NOTIFICATION ON (if it is off).  Also be sure to turn VIDEO_8514A_XGA_IO_TRAPPING OFF (default is ON) or screen performance in WINOS2 sessions may be sluggish.

If you have icons on the PM desktop for individual Windows applications, you should perform the same settings on each of them as are recommended for the WINOS2 command prompt.

Keep in mind, too, that you should not attempt to switch from the full-screen WINOS2 to the PM desktop while a Windows application is actively drawing to the screen.  If you do so, you are likely to disrupt the video synchronization of the WINOS2 desktop when you switch back.

Finally, keep in mind that the Stealth VRAM drivers in this release do not virtualize resolutions greater than 640x480 for DOS applications.  If you wish to run a high-resolution DOS application (other than Windows), exit the application before you attempt to switch back to the PM desktop.

V.	Known problems

     	Here are the known problems in release 1.1 of the Stealth VRAM OS/2 2.x drivers.

1.	Problem:  In a full-screen WINOS2 session, you may find cursor movement to be jumpy.

	Solution:  Close the full-screen WINOS2 session.  Select the WINOS2 icon on the PM desktop and bring up its SYSTEM MENU (click the right mouse button).

	Select OPEN then SETTINGS from the menu.

	Select the SESSION tab in the SETTINGS notebook.

	Select the WIN-OS/2 settings button (or DOS settings button).

	Set the following three items:

	       IDLE_SECONDS             	to	20
	       IDLE_SENSITIVITY         	to	100
	       MOUSE_EXCLUSIVE_ACCESS   	to	ON

	Select the SAVE button and CLOSE the SETTINGS notebook.

2.	Problem: When WordPerfect 5.1 is installed on the Stealth VRAM it incorrectly identifies the Stealth's S3 video chip as an ATI video chip.  If you then switch from the WordPerfect Print View (graphics-mode) screen to the PM desktop, the Print View screen will be incorrectly restored when you attempt to return to it.
 
	Work-around:  Go into WordPerfect's Setup function <Shift>+<F1>, select DISPLAY, then GRAPHICS SCREEN TYPE, and select the IBM VGA (& compatibles) option.

3.	Problem:  When running a seamless Windows session under OS/2 2.0 GA (i.e., WITHOUT the Service Pak), closing a Windows application in the normal way--from the File menu, the System menu, or the Close box--may leave it running in the background even though it has disappeared from the screen.

	Work-around:  Close the application from the OS/2 PM Window List instead of from the application's menus or Close box. (Running the seamless Windows function under OS/2 2.0 GA is NOT recommended!)
