****************
* KIT CONTENTS *
****************

This distribution kit contains the Windows NT device drivers for 
the Digital Fast EtherWORKS PCI 10/100 adapter (DE500).

Alpha, Intel, MIPS, and PPC platforms are supported for Windows 
NT 3.51 & 4.0.

****************
* INSTALLATION *
****************

For general installation instructions, refer to the "Windows NT 
System Guide".  The chapter on the "Control Panel" contains a 
section that describes the installation of network cards in detail.

***********************************
* UPDATING FROM PREVIOUS VERSIONS *
***********************************

Normally, driver updates are performed using the "Update" button 
under the Network Settings option in the Control Panel.  However, 
the final release of Windows NT 3.51 and 4.0 only searches for 
the file "OEMSETUP.INF" during "Update", while selecting "Add 
Adapter" searches for both "OEMSETUP.INF" and "OEMSETNT.INF" files.  
Driver updates can be performed by removing the adapter(s), 
rebooting, then installing the new driver, then rebooting.

Do NOT merely uncompress and copy the driver on this diskette to    
the appropriate directory on NT.  The driver keywords sometimes
change between versions, making it important to use the normal
installation remove/add procedure.

*****************
* CUSTOMIZATION *
*****************

For most configurations, no customization of the driver should be 
necessary.  After installing the WINNT driver, click on the 
"Configure" button after highlighting the desired controller under
"Network Settings". For help on any of the selections that appear 
in the dialog box just click on the "Help" button.

**********************************
* INTERPRETING EVENT LOG ENTRIES *
**********************************

Note: During runtime operation, the NDIS wrapper enables a 
      "watchdog" timer which polls the driver regularly to verify 
      that it is operational. If the driver returns non-operational
      status, the operating system will reset the driver.  If the 
      reset is successful, the driver returns to normal operation.  
      Otherwise, it is halted.  This process is automatic and does 
      not require user intervention.  However, should the system 
      performance become sporadic with constant driver event logger 
      entries being added, verify that the driver is not being 
      constantly reset.  If it is, shutdown the machine and run the
      adapter diagnostics.

When the driver detects errors, it may write entries into the event 
logger.  To interpret the error code, examine the entry that was 
written by the driver and read the last longword that is contained 
in the entry. The meaning of each of the longwords can be found in
the Fast EtherWORKS PCI 10/100 Help File. This is accessed by
clicking on the "Help" button that appears in the dialog box used
to configure the Fast EtherWORKS adapter.
