****************
* 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. Alpha and Intel platforms are supported for Windows 
NT 3.50.

****************
* 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 3.5 and 3.51 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. 

*****************************************************
* INSTALLING MULTIPLE DE500'S IN AN NT3.5 SERVER PC *
*****************************************************

When installing multiple cards, identifying which card is seen 
first is system dependent.  When installing cards of different 
types (ex. DE450 and DE435), this is unimportant.  When installing 
cards of the same type (Ex. DE450 and DE450), for different media 
(ex. TP and BNC), which card is seen first becomes important.  The
best option is to choose "AutoDetect" for the media, then it will 
not matter which is seen first.

With the NT3.5 Server running do the following to install the first 
adapter:

1. In the MAIN Group double click on the "Control Panel" Icon.

2. In the Control Panels group double click on the "Network" Icon.

3. In the "Network Settings" window click on the "Add Adapter" 
    button.

4. In the "Add Network Adapter" window click the down arrow on the 
    right side of the "Network Adapter Card" window. Scroll to the 
    bottom, click on the "<other> Required disk from manufacturer", 
    click on Continue.

5. Then the "Insert Disk" window comes up.  Click OK for A:\
    Note: Make sure the floppy is installed in the floppy drive.
    click on OK.

6. A "Select OEM Option" window comes up. Select the DE500
    adapter, then click OK.

7. The drivers should now be copied from the floppy onto the NT
    system's hard drive.

8. In the "Network Settings" window is a "Installed Adapter Cards" 
    window. The adapter name should appear there.

9. Select the adapter that was just installed in the "Installed
    Adapter Cards" window and click on configure.

10. Set the Bus Number to the proper value for the first card that
     is being installed. On most systems this will be 0. Also
     select the desired Card Instance number. For the first card on
     the selected bus choose 1, for the second choose 2, and so on.

11. Select OK to exit the dialog box.

To add the Second adapter do the following:
-------------------------------------------

12. In the "Network Settings" window click on the "Add Adapter" 
     button.

13. Add the adapter in the same manor as done in steps 4 through 9.

14. Configure the adapter and set the proper Bus Number and Card
     Instance for the second adapter. If the adapter is on the same
     bus as the first adapter, just set the Card Instance to 2. If
     the card is on a different bus set the Bus Number to the
     correct value and the Card Instance to 1. Keep in mind that the
     specified Card Instance is for the specified bus.

To add additional adapters do the following:
--------------------------------------------

15. Follow steps 12 through 14 but just set the Bus Number and
     Card Instance as necessary for each adapter.
