                          files required for installing the driver using
                          netcfg, in particular:
                            - netcfg related scripts and Drvmap files.

                            - Space.c, the parameter file
---------------------------------------------------------------------



5. Installing the Hardware Boards:

   Installing the Intel 21040/21140/21140A/21041/21142/21143 PCI Evaluation
   Board

   To install the EB40 or EB140 or EB41 or EB140A-TX or EB142 see the Intel
   21040 PCI Evaluation Board User's Guide or the Intel 21140 PCI Evaluation
   Board User's Guide or the Intel 21041 PCI Evaluation Board User's Guide or
   the Intel 21140A PCI Evaluation Board User's Guide or the Intel 21142 PCI
   Evaluation Board User's Guide or the Intel 21143 PCI Evaluation Board User's
   Guide.



6. Installing Software:

   To install the SCO Unix GEMINI Device Driver:

   Copying the distribution files
   ------------------------------

   -  Create/Choose a temporary directory (e.g. /tmp/install), use:
          mkdir /tmp/install

   -  Change the current directory to the above directory, use:
          cd /tmp/install

   -  Copy the file SUG430TD.PKG to this directory.
      For DOS file, use: 
          doscp SUG430TD.PKG .
      The number in parentheses near the file's name (above) is the checksum
      for the file. To verify, use:
          sum -r SUG430TD.PKG
      and compare the results.

   - Remove any previously installed versions using:
	  netcfg
	  pkgrm d21x

   TO USE THE PACKAGE FILE DIRECTLY:

   - Install the package using:
          pkgadd -d /tmp/install/SUG430TD.PKG

   CONTINUE THE INSTALLATION PROCESS:

   -  Run netconfig. Add the desired chain. The d21x drivers are called:
      "Intel 2104x based 10 Mbps Ethernet Controller" and
      "Intel 2114x based 10/100 Mbps Ethernet Controller"

      During this process a dialog will allow you to modify the advanced
      option. This option allows the user to override the medium type chosen
      by the board designer. We advise users not to change the default
      settings unless really necessary. The same dialog can be reached after the
      installation is compeleted through the "Modify Hardware Configuration"
      item in netcfg's "Hardware" menu.

         NOTE: For boards with more than one Intel 21X4X on
               them, a driver must be installed for each active port on the
               board. Thus, if a board has two separate ports, two separate
               chains must be created in order to connect both ports to
               networks. This is similar to installing two boards, each with
               one port.

               Not all ports must be active.

   -  When the chain has been configured, select "Exit" from the netconfig menu.

   -  If you wish to change parameters in the space.c file, edit
      /etc/conf/pack.d/d21x/space.c and make the required changes.
      When finished, Relink the kernel manually using:

		/etc/nd stop
		/sbin/modadmin -U d21x
		/etc/conf/bin/idbuild -M d21x
		/etc/nd start

   - In some versions of UnixWare 7 you must reboot the machine in order for
     some of the changes to take effect. In others it is enough to do the
     following:

		/etc/nd stop
		/sbin/modadmin -U d21x
		/etc/nd start



7.  Parameters

   The space.c file contains the different parameters that can be modified.
   They can be divided into several groups:

   1. Port parameters. These include:
         XXX_BUS_ARBITRATION
         XXX_BURST_LENGTH
         XXX_CACHE_ALIGNMENT
         XXX_PASS_BAD_FRAMES
         XXX_BACKOFF_CNTR
         XXX_10MB_THRESHOLD
         XXX_100MB_THRESHOLD
         XXX_PARITY_ERROR_RESPONSE
         XXX_LATENCY_TIMER
         XXX_CRC_CALC
         XXX_DC2114X_GPR_CTRL
         XXX_DC2114X_GPR_DATA
         XXX_TURBO
         XXX_SNOOZE
         XXX_MWI,		/* Enable/Disable MWI extended PCI command */
         XXX_MRM,		/* Enable/Disable MRM extended PCI command */
         XXX_MRL		/* Enable/Disable MRL extended PCI command */
         XXX_0_MAC_ADDR
         XXX_1_MAC_ADDR
         XXX_2_MAC_ADDR
         XXX_3_MAC_ADDR
   2. Driver tuning parameters:
         XXX_RX_BUFS_TO_POST

   3. Driver diagnostics control:
         XXX_DEBUG

   The meaning of each is explained in detail in the space.c file, including
   allowed values for each parameter. The values in space.c apply to ALL
   the installed boards, except the MAC address parameter.

   Space.c is NOT the place to modify the board's slot number line.
   This must be modified in netcfg, by running the reconfiguration "resmgr"
   script.

   The serial mode interface can be changed during netcfg as explained
   before.



8. Errors and trouble shooting


   1. Mismatch between PCI configuration and netconfig/space.c:

      In order for the adapter to work correctly, the same values that are
      used during the PCI configuration (e.g CFLT) must be used in the
      space.c file. Mismatches may cause the adapter to malfunction, or even
      hang the system.

      Currently, the PCI setup takes precedence except for the value for the
      latency timer, which is taken from the space.c file.



9. Driver's error messages (when working in debug level > 0)

In "d21xi" the 'i' stands for a number between 0 and 3, indicating
the particular instance of the driver the message is reported by.

  * "d21xi Could not intialize driver, PCI BIOS couldn't read/write configuration register"

    This message will be printed in PCI board - if can't read or write the
    configuration registers when using the PCI BIOS.

  * "d21xi Could not intialize driver, found PCMC revision.1 with write-back cache mode"

    This message will be printed in PCI board - if PCMC rev.1 chip was found
    and it works with write-back cache mode (this mode can cause crash in the
    driver).


  * "d21xi Could not intialize driver, unsupported PCI board - DC21040
     revision.1"

    This message will be printed in PCI board - if it is a board with Intel
    21040 revision 1 on it.

    line to the interrupt handler.

  * "d21xi Could not intialize driver, unsupported interrupt line was set by the PCI BIOS to CFIT"

    the user or read from the SROM (in case the user choose to use the SROM
    value) for the serial interface of Intel 21041 or 21140
    or 21140A or DC21142 or DC21143. And in boards with Intel 21040 -
    if unsupported serial mode was choose by the user for the serial
    interface of Intel 21040

     AUTOSENSE and there are GPR values in space.c that override the defaults.
     Either select serial mode explicitely, or set the GPR values in space.c
     back to the default values (see space.c).

Download Driver Pack

How To Update Drivers Manually

After your driver has been downloaded, follow these simple steps to install it.

  • Expand the archive file (if the download file is in zip or rar format).

  • If the expanded file has an .exe extension, double click it and follow the installation instructions.

  • Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.

  • Find the device and model you want to update in the device list.

  • Double-click on it to open the Properties dialog box.

  • From the Properties dialog box, select the Driver tab.

  • Click the Update Driver button, then follow the instructions.

Very important: You must reboot your system to ensure that any driver updates have taken effect.
