Adding or removing hardware controllers

Removing hardware controllers

The UnixWare system automatically detects when some controllers (for example, supported EISA, MCA, or PCI hardware) are installed on the system. If such controllers are removed from the system, the device driver parameter settings for the controller are automatically removed from the system resource database.

However, if the UnixWare system cannot detect whether a controller is installed on your system, the controller's device driver parameter settings are not automatically removed from the system resource database when you remove the hardware. ISA controller settings must be removed manually using the Device Configuration Utility (DCU). General information about the DCU is available in ``Using the Device Configuration Utility (DCU)''.

You can use this procedure to remove ISA hardware components from your system.

  1. From the DCU main menu, select Hardware Device Configuration.

  2. From the "Hardware Device Configuration" screen, move the cursor to the row containing the device driver settings for the controller.

  3. Exit the "Hardware Device Configuration" screen.

  4. Select Apply Changes & Exit DCU.

  5. If you are removing a controller from your system, decide whether the device driver parameter settings for the controller should be removed from the system resource database.

  6. Select Apply Changes & Exit DCU.

  7. Shutdown the system.

  8. When prompted, turn off the system power switch.

  9. If the hardware peripheral(s) have power switches, turn them off.

  10. Remove the hardware controller(s) or peripheral(s).

  11. Turn on the power for all devices that are connected to your system.

  12. Rebuild or reboot the system. See `` Rebuilding your system''.
