SCO UNIX MDI Driver Installation
================================

A. Software Revision Requirements:

    1. OpenServer or higher version, or
       SCO Unix 3.2.4 or higher version
    2. SCO AHS (for versions prior to OpenServer 5.0.2)


B. Installing Driver:

   1. Copy the file SUM430TD to a SCO Unix machine.

   2. Rename it to VOL.000.000 using:
         mv SUM430TD VOL.000.000

   3. Run custom. From the menu select:
      Software -> Install New -> From Host -> Volume Image -> Full
      And give the path for the volume image file.

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

         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.

   5. You can change the default value of the media by using the
      "Advanced Options..." option in the menu.

   6. When the chain has been configured, select "Exit" from the netconfig menu.
      If you don't wish to modify the space.c file relink the kernel at the
      prompt.

   7. 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/conf/cf.d/link_unix

   8. Reboot the system.


C. 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 netconfig, by running the reconfiguration
   script.

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

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.
