Changes made in this diskette, version 1.00:

- none, installation program is unchanged.  Only driver file is
  updated.


3.0   Installation and Configuration
____________________________________


The batch file, B57NT4UD.BAT, 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.BAT batch file) can be in one path and
driver files located in different directory.

The B57NT4UD.BAT 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

The batch file will display a usage message with a '?'
parameter: B57NT4UD ? In case of a missing required driver file, the
computer displays an error message.
