This update package performs unattended software updates under 
Windows NT 4.0.

It supports upgrading software from SW Release 1.x to SW Release 2.x 
or to SW Release 3.x, or from SW Release 2.x to SW Release 3.x
and future releases.  Currently, it does not support downgrading to 
a prior version. 

The batch file, NTUPDATE.BAT, can be invoked via command line options. 
It upgrades the software silently by copying the files and updating 
the registry and, if specified, restarts the computer.

The NTUPDATE.BAT batch file can be run from any path but the NT 4.0 
OEMSETUP.INF file, the associated software and the NTUPDATE.INF file
must be located in the same directory.

The batch file can be executed as stand-alone by providing the 
command line options or hooked to another package. The NTUPDATE.BAT
can be invoked as follows:

	NTUpdate SourcePath INFOption RebootOption
	or	
	NTUpdate SourcePath RebootOption
	or	
	NTUpdate RebootOption
	or	
	NTUpdate

where: 
        NTUPDATE            the name of the batch file 

        SourcePath        : the absolute path to the upgrade software
                            This is an optional parameter;
			    the default is the current directory

        InfOption         : used to pass the INF option for the 
			    OEMSETUP.INF file
                            This is an optional parameter;
			    if not specified, it is auto-detected.

        RebootOption      : indicates whether to restart the
                            computer after the update is performed. 
                            The options are: 
                               0 = no restart
                               1 = restart without prompting user
                               2 = restart by prompting user


For example, to update to the 3.x software from the location 
"d:\update3", with no restarting after the update option, type the 
following command:

        NTUPDATE d:\update3 0

During the update, progress bars are displayed.  Update results are written 
to a log file named after the COMPUTERNAME with a '.log' extension in the, 
%systemroot%\system32 directory, for example: 
	"C:\WINNT\SYSTEM32\WORK_STATION_16.LOG".  
A zero in this file indicates the update was successful, otherwise the update
failed.  The update will take effect at the next restart of the computer.

The batch file will display a usage message with a '?' parameter: NTUPDATE ?
In case of a missing required driver file, the computer displays an 
error message.
