Dell GX1 Saving the System Configuration, Exiting From the ICU, Locking and Unlocking Cards

Using the ISA Configuration Utility: Dell OptiPlex GX1 Low-Profile Managed PC Systems

You can save the information displayed in the Card Resource Usage dialog box by clicking Print To File. The ICU then prompts you for a filename.

Saving the System Configuration

You can save the system configuration to nonvolatile random-access memory (NVRAM) as you configure each card's resources. To do so, select Save from the File menu and continue with your operation.

Exiting From the ICU

At the ICU window, select Exit from the File menu to exit the utility. If you have made any changes to the system configuration, you are asked whether you want to save the changes.

If you click Yes, the ICU saves the updated system configuration information into NVRAM. If you click No, you exit the ICU without saving any of your configuration changes. If you click Cancel, nothing is saved and the utility continues to operate.

Locking and Unlocking Cards

The ICU includes a locking mechanism that enables you to allocate the system resources for all or for some functions of Plug and Play and PCI expansion cards. These expansion cards are dynamic, which means that they are allocated resources at system start-up. Device drivers that do not support this dynamic card configuration are referred to as static device drivers.

To determine whether your expansion card has static device drivers, check the documentation that came with the drivers. If you are using a static device driver, you need to permanently associate resources with a Plug and Play expansion card, instead of relying on the default Plug and Play behavior. Otherwise, the device driver might not be able to find the card the next time the system boots. This procedure is referred to as locking a card.

NOTE: The locking feature of the ICU is valid only for Plug and Play and PCI expansion cards.

Locking and Unlocking All Resources

To lock or unlock all the resources and configurations for a Plug and Play or PCI expansion card, perform the following steps:

1.If it is not already installed, install the Plug and Play or PCI expansion card. Then turn on the system. Complete steps 2 through 10 in "Installing an Expansion Card."

2.Start the ICU.

See "Starting the ICU."

3.Select Locking Enabled from the Advanced menu in the ICU window.
