Microsoft Windows NT, Beta March 1993
Patch for IBM XGA and XGA II Video Problems


The Microsoft Windows NT product group has recently identified a video problem 
with the March Beta release of Windows NT.  If you have installed the Beta 
March release you may encounter problems running IBM XGA systems in the XGA 
high resolution modes.  The XGA driver executes only in VGA mode regardless 
which resolution is selected.

If you encounter this problem, please take the following steps to remedy this 
behavior.  We appreciate your efforts in reporting problem areas and encourage 
you to continue working with us to improve the product. We apologize for any 
inconvenience this may have caused.

To retrieve the corrected files from the WINNT CompuServe forum:

    Connect to the WINNT CompuServe forum, Library 2 where you will find 
    WNT009.ZIP.  This file was created using the PKZIP file compression 
    utility.  You will need the PKUNZIP utility to extract the files to
    a directory on your hard drive.  PKUNZIP can be found as PKZ110.EXE 
    in Library 2 of the IBMCOM forum.  Download PKZ110.EXE and execute 
    the file to extract the PKUNZIP.EXE utility.  Create a directory on
    your hard disk where the extracted files can be placed.  For example, 
    C:\WNT009.  To extract the WNT009.ZIP file, type: 
	PKUNZIP WNT009.ZIP C:\WNT009
    to decompress the files into the directory.  The following files can 
    now be seen:

	NTDETECT.COM
	XGA.SYS
	README.TXT

Instructions to resolve the problem behavior:


1.      Logon to Windows NT as Administrator or with administrative privileges.  

2.      Execute the MS-DOS Command Prompt from the Program Manager.

3.      Locate NTDETECT.COM on the system boot drive, normally C:\, and change 
the attributes of this file at the command line by typing, 
ATTRIB NTDETECT.COM -H -S -R.

4.	Insert the floppy patch disk into the floppy disk drive and at the 
command line type, COPY A:\NTDETECT.COM C:\.

5.      Change the attributes of NTDETECT.COM again by typing,
ATTRIB NTDETECT.COM +H +R +S.

6.      Locate XGA.SYS on the system hard drive in the Windows NT system 
drivers path.  For example, CD \WIN31\SYSTEM32\DRIVERS or change directories 
to the appropriate system drivers directory for your Windows NT installation 
where XGA.SYS is located.  

7.	With the floppy patch disk in the floppy disk drive, copy the updated 
file to replacing the failing one.  For example, type 
COPY A:XGA.SYS C:\WIN31\SYSTEM32\DRIVERS.

8.      Exit Program Manager and shutdown from Windows NT by pressing 
CTRL-ALT-DEL, and select Shutdown, then OK.  You may now log back on and 
proceed as normal. 

9.	If you wish to change the video resolution for your system, execute 
Windows NT Setup from the Main program Group.  Select Options, Change System 
Settings.
