Installing and configuring UDI drivers

To install and configure a binary UDI driver on an SCO OpenServer system:

1. As root, add the UDI package to your system.

   If the UDI package is provided in a tar archive, or a custom or pkgadd package, use the corresponding tools to install the UDI package on the system.

2. Run the udisetup(ADM) command to install and configure the UDI driver into the kernel. The current working directory is searched and driver files are extracted from all .udi and .UDI package files that are found. The udisetup utility then installs the drivers in environment-specific locations and prepares the drivers for use on the system.

3. Configure the corresponding device using the standard system utilities. For example, to configure a Host Bus Adapter (HBA) to use a UDI HBA driver, you must run the mkdev hd utility.

   If you are configuring a network adapter, see ``Configuring UDI network devices''.

Configuring UDI network devices

Under normal circumstances, network devices are configured with corresponding drivers using the Network Configuration Manager. If a UDI driver is installed on the system and there is no native driver (MDI) installed for the target driver, the Network Configuration Manager will correctly detect and configure the new UDI driver.

However, if a UDI network driver is installed to support a network device for which a native driver is already installed, the Network Configuration Manager might fail to detect the UDI driver.

If you have native and UDI drivers for the same network device on your system, there are two ways to get the UDI driver to work.

• If you do not need the native driver on your system, remove it using the Software Manager, relink the kernel, and reboot the system.

  For example, if you want to remove the native driver for an Intel Pro/100 device, you would remove the eeE driver package. You can then use the Network Configuration Manager to configure the remaining UDI driver.

• If you do not want to remove the native driver, you must make it temporarily unavailable while you configure the UDI driver. Using the Intel eeE driver as an example, you would:

  1. Login as root.

  2. Start the Network Configuration Manager.

  3. Open a UNIX window and enter:
     
     cd /var`/etc/llipathmap`/ID/eeE
     
     mv AOF AOF-

     This prevents the Network Configuration Manager from finding the native driver.

  4. On the Network Configuration Manager main screen, select Add LAN Adapter. The manager scans the PCI configuration space and matches the eeeudi driver package.

  5. In the UNIX window, restore the directory that you moved earlier:
     
     mv AOF- AOF

     Performing this step now avoid linktime errors.

  6. Continue configuring the network device in the Network Configuration Manager. When finished, answer Yes to relink the kernel and reboot the system.
