# Installing MDGMPORT.SYS after Windows NT installation

To install the drivers:

1. Start up your Windows NT station, and logon as an Administrator.

2. From the Control Panel, select the Networks icon. The screen displays the Network Settings window.

3. In the Network Settings window:

   - If you are installing drivers for the first time, click on Add Adapter.

   - If you are changing drivers, click on Remove, and delete your adapter entry. Then click on Add Adapter.

4. From the list, select requires a disk from manufacturer.

5. Insert the Madge release disk, as prompted, and type the path of the Madge drivers.
   For example: A:\ .

   NT displays a list of Madge adapters that may be installed and an option called "Madge Automated Smart Ringnode Installation".
   If you select automated installation, the Madge installation program will search your computer for Madge Smart Ringnodes and attempt to determine any hardware settings (IRQ number and DMA channel). If you do not use automated installation, you will have to supply all of the hardware settings required by the driver yourself. We recommend that you use automated installation. Select automated installation or an adapter type. If you have selected an adapter, proceed to step 8.

   | Automated installation does not find 16/4 PCI Ringnodes under NT 3.5 (it does under NT 3.51). To install a 16/4 PCI Ringnode under NT 3.5, select the "Madge Smart 16/4 PCI Ringnode" or "Madge Smart 16/4 PCI (BM) Ringnode" and proceed to step 8.

6. After a short pause a dialog box will appear that lists all of the Madge Smart Ringnodes present in your Machine. Select the one you wish to install and click on OK.

7. The screen displays a Madge dialog box that describes the configuration of your adapter. Depending on the type of adapter you have, the dialog box will contain different configuration options. Most of the options correspond to the hardware configuration of your adapter. To the right of each of these hardware configuration options will be displayed the option setting which the installation program thinks your adapter is currently configured to. Any option settings that could not be determined by the installation program will be marked as "UNKNOWN". For all of the options marked as "UNKNOWN" you must set the value that matches the configuration of your adapter (as set by the switches on older adapters or by the "Madge Wizard" configuration utility on newer adapters).

   For further information on the hardware configuration, click on the HELP button in the Madge dialog box.

   | For Madge PCI Ringnodes, if you do not know the PCI Device Number of your Ringnode (your PC's configuration utility may tell you the PCI Device IDs of the PCI adapters in your machine), leave the "PCI Device ID" option set to "UNKNOWN". If you do this, MDGMPORT will use the first 16/4 PCI Ringnode it finds in the computer. (If you install a second copy of MDGMPORT for a 16/4 PCI Ringnode in the same way, then this instance of MDGMPORT will find the second 16/4 PCI Ringnode.)

8. You can also use the Madge dialog box to set a different maximum frame size from the default. On some adapter types you may set the ring speed. A Locally Administered Address for your Ringnode may also be set. (If you are setting an LAA you can make it easier to read by separating every two digits with a hyphen.)

   The Madge Dialog Box contains a list box which allows you to choose the number of receive and transmit buffers to use. If your machine is a '486' or Pentium class PC being used as a personal workstation then leave this setting at its default (RX=04 TX=04). If your machine is a high performance RISC platform or a machine being used as a server then you may wish to increase the buffer allocation. Note that if you have multiple adapter cards in a server and a large maximum frame size then you have to use fewer buffers to avoid running out of memory.

9. Click on the CONTINUE button.

10. When prompted, restart the computer.
