2. Overview:

           This Readme file explains how to install the Windows NT driver 
           for x86-based platforms.  The driver is currently supported for 
           the SMC 8432 PCI Ethernet Controller and the SMC 9332 PCI
           Fast Ethernet Controller.


3. Requirements: 

   A.  Hardware Requirements:

      o An IBM-compatible personal computer with 80386 or higher microprocessor
        and EISA or PCI bus.

      o A DECchip 21040-based Ethernet adapter or a DECchip 21140-based Fast 
        Ethernet adapter for that bus.


   B.  Software Revision Requirements:
 
             Windows NT Version 3.1 or later

5. Installing the Hardware Boards: 

   A. Installing the SMC 8432 PCI Ethernet Controller:

      To install the SMC 8432 see the board's User Guide.

   B. Installing the SMC 9332 PCI Fast Ethernet Controller:

      To install the SMC 9332 see the board's User Guide.




6. Installing the SMCPWRN NT Driver Software: 

   1. From the Windows NT Main Menu, select the Control Panel icon. 
              
   2. From the Control Panel menu select the Network icon.
      If a dialog box asks you "Do you want to install NT
      Network?" select YES and Continue. Then place
      the Windows NT CDROM in the CD-ROM reader. 
              
      Select the drive that matches the configuration of your system 
      and complete the install. 
              
   3. You will see several messages. To add a network adapter, select Yes 
      and then Continue 
              
   4. For each additional message, select continue. 
              
   5. From the Add Network Adapter dialog box, scroll through the menu to 
      select Other. 

   6. When the Insert Diskettes menu prompts you for a disk, insert the 
      SMCPWRN driver installation diskette for Windows NT into drive A. 
      Then select OK. 

   7. Select your option
             [SMC 8432 PCI Ethernet Controller      ]
             [SMC 9332 PCI Fast Ethernet Controller ]
      from the Select OEM Option box, then select OK.

   8. Modify the default distribution path in the Windows NT [tm]
      Setup box to point to the correct drive and path, then click 
      on [Continue]

   9. For PCI options, a Dialog box pops up to select the:
 
      ConnectionType:

         o AutoDetection               In AutoDetection mode the driver
                                       checks first the Twisted Pair port. 
                                       If the Link Test fails the driver 
                                       checks the BNC Thinwire port. If no
                                       carrier is detected the driver switches
                                       to the AUI Thickwire port.
         o Twisted Pair 
 
         o Twisted Pair-Full Duplex    To connect to Full Duplex hubs
 
         o Twisted Pair-No Link Test   To connect hubs not supporting 
                                       the Link Integrity Test
         o BNC-Thinwire                BNC connector

         o AUI-Thickwire               15_pin connector

   10. Upon completion, one of the following adapters
             [ [n]SMC 8432 PCI Ethernet Controller       ]   
             [ [n]SMC 9332 PCI Fast Ethernet Controller  ]
      appears in the Installed Adapter Cards list of the
      Network Setting box (n is the adapter number).

   11. Click on [Close] to complete the Network Setting
       initialization.

   12. If needed, modify the values in the registry (see section 7 below).

   13. Shutdown and reboot the system.


   14. Installing multiple PCI boards:

      Repeat the procedure above.



7. Parameters

   To overwrite the driver default values, add or edit the 
   following values in the Registry SMCPWRN_<adapter_number> Parameters 
   subtree:
          NetworkAddress = REG_SZ { xx-xx-xx-xx-xx-xx }

                  Mandatory if no Serial ID PROM is plugged in
                  Overwrite the Serial ID PROM if plugged in
                  NetworkAddress 00-00-00-00-00-00 is ignored

        SoftwareCRC = REG_DWORD { 0 |  1 }  (rev 1.x, 2.0 & 2.2 only)

                  0 The CRC is generated by the adapter
                  1 (default) The CRC is generated by software for 
                    transmit packets bigger than the transmit threshold. 

                  NOTE: This option affects performances and could be 
                        disabled if the adapter does not report transmit 
                        underflows in its statistic counters

       The following values allow to overwrite the SMCPWR default setting.
       Refer to the DECchip 21040 & DECchip 21140 Engineering specifications 
       for detailled description:

			0 - detect system's PCI mechanism automatically
			1 - force PCI mechanism #1 accesses to the 
			    PCI configuration space
