Goal:
==============================================================================
This package performs unattended update of network adapter drivers under
Windows NT 4.0 for Broadcom network adapters.


Compatibility:
==============================================================================
Require Broadcom Gigabit Ethernet Controller NT 4.0 driver.


Files in the package:
==============================================================================
B57NT4UD.EXE    - Program file to update NIC drivers.
B57NT4UD.INF    - Inf file for unattended update.
B57NT4UD.TXT    - This text file.


Information:
==============================================================================
The program file, B57NT4UD.EXE, can be invoked via command line options. 
It upgrades the network adapter driver silently and, if specified, restarts
the computer.

This package and driver files can be all in one directory. Or, this package
(including B57NT4UD.EXE file) can be in one path and driver files located in
different directory.

The B57NT4UD.EXE usage is as follows:

    B57NT4UD [RebootOption [SourcePath]]

where:
    SourcePath   : absolute path to the driver files
                   default is the current directory

    RebootOption : 0 no reboot  - default
                   1 reboot the machine without prompting the user
                   2 reboot the machine by prompting the user

Example 1: this package is in 'f:\Update\WinNT' and driver is in 'f:\', with
no rebooting machine option, do the following steps:
a) Change directory to 'f:\Update\WinNT'.
b) Type the command 'B57NT4UD 0 f:\'.

Example 2, this package and driver files are all in 'c:\temp' and with no
rebooting machine option, do the following steps:
a) Change directory to 'c:\temp'.
b) Type the command 'B57NT4UD 0'.

During the update, progress bars are displayed briefly. Update results are
written to a log file which name is concated by the COMPUTERNAME, '_' and
driver name with a '.log' extension. The log file is in the
%systemroot%\system32 directory.
For example: "C:\WINNT\SYSTEM32\MYCOMPUTER_B57NT4.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.

B57NT4UD also writes "Pass" or "Fail" to the "Unattended Update" value at 
registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Broadcom\B57NT4
