This document describes the procedures for using the 3Com NIC Driver 
Update Kit to upgrade your driver and diagnostic program to the version 
of the software that was included on the EtherDisk (R) Diskette version 
5.0 for the 3C90x Fast EtherLink XL/EtherLink XL PCI Bus Master NIC 
Family.  The 3Com NIC Driver Update Kit makes it possible to update 
your network software without having to use the control panel.  It can
also be used to update many systems on a network automatically by 
using NetWare login scripts or software version management system.

1) The update program will run on Windows 95, Windows 98, Windows NT 3.51 
   and Windows NT 4.0.

   installed in the system.

Using the Driver Update Kit in a multi-NIC environment
======================================================
Updating a 3C90XB or 3C905C NIC to EtherDisk 5.0 in a system that also  
contains a 3C900 or 3C905 NIC will cause the 3C900 or 3C905 NIC to stop 
functioning.  If you wish to keep multiple NICs on your system and mix 
3C900 or 3C905 NICs with newer NICs, you must first remove the driver 
for the 3C900 or 3C905 NIC, via the Network Control Panel, and then 
re-install these NICs with a software update which is available on the 
3Com support world wide web site.  After re-installing the 3C900 or 
3C905 NIC with the software update, you can proceed with the updating
your system to EtherDisk 5.0 by running the 3Com NIC Driver Update Kit.

To download the software update, you must use the link
http://support.3com.com/infodeli/tools/nic/index.htm on the 3Com support 
world wide web site.  Use the pull down menu to choose the product number 
for your NIC (3C900 or 3C905).  Look for the heading "3C900/3C905 
Multi-NIC Update for use with EtherDisk/EtherCD 5.X" and follow the 
instructions on the web page to download the software update.

Updating the Driver without installing the Diagnostic Program
=============================================================
The 3Com NIC Driver Update Kit can be called with the command
line parameter /nodiag.  Using this parameter will update the
driver without installing the Diagnostic Program.

		Update.exe /nodiag

The 3Com NIC Driver Update Kit in Unattended Mode
=================================================
The 3Com NIC Driver Update Kit has two command line parameters that allow
it to be used for unattended upgrades or to be used in software management 
applications to push the upgrade to the end-stations.  The first option,
/unattended, suppresses all dialog boxes so no user interaction is needed
to perform the upgrade.  
The second, /preload, should only be used if the Driver Update Kit is 
called during the installation of the Operating System, or OS, and delays 
the installation of the 3Com Diagnostic Communication Protocol until the 
OS has finished its installation.  Since running the Driver Update Kit 
during the OS install requires special software from Microsoft, like the 
OPK, if you are unsure on whether to call the /preload parrameter we suggest
you attempt the OS install without this parrameter first and only if this 
does not work should you use the /preload parameter.

		Update.exe /unattended [/preload] [/nodiag]
