Microsoft Windows NT, Beta March 1993 
S3 resolution and Dell systems with S3 video chipset installation problem


The Microsoft Windows NT product group has recently identified three video 
problems with the S3 chipset.  When installing the Windows NT Beta March 
release on a Dell system with the S3 chipset, you may encounter a blank screen
at the conclusion of text based Setup as graphical Setup is loaded preventing 
the installation of the Beta March release of Windows NT.  Alternatively, if 
you have successfully installed the Beta March release and later attempted to 
utilize the S3 driver which may have resulted in a blank screen on reboot,
or experience screen flicker or other video related problems using the S3 
driver, please take the following steps to replace the files as instructed 
below to resolve the problem. 

We appreciate our customers efforts in reporting problem areas and encourage 
you to continue working with us to improve the product.  If you continue to 
encounter similar problems please let us know.

at the conclusion of text based Setup, please take the following steps: 

1.	Reboot the system by pressing CTRL-ALT-DEL or power the system off, 
then on.

installation of Windows NT and change the video driver after Windows NT has 
been installed beginning with Step 1 in Section C.   


Section B

If you have successfully installed Windows NT and later attempted to install
the S3 driver provided in the Windows NT March release which may have resulted 
in a blank screen on reboot, please read the instructions below to resolve 
this behavior.

1.	Boot MS-DOS or an alternate operating system. 

2.	Locate S3.DLL on the hard drive in the Windows NT system path.  For 
example, CD \WIN31\SYSTEM32.  At the command line, type, 
RENAME S3.DLL S3DLL.OLD.

3.	Locate S3.SYS on the hard drive in the Windows NT system path.  For 
example, CD \WIN31\SYSTEM32\DRIVERS and type, RENAME S3.SYS S3SYS.OLD.  

4.	Windows NT will now use the VGA.SYS driver.  Reboot the system and 
select Windows NT from the Boot Loader to complete the installation of the
updated S3 driver beginning with Step 1 in Section C below.

settings and choose the appropriate S3 resolution entry and press enter. 

6. 	If you were previously using the failing S3 driver, you will be 
prompted by a dialog box asking if you wish to use the current driver or 
a new one.  Select new.  

7.      In the Insert Diskette dialog, type the floppy drive letter where
the patch diskette is located and choose OK.
