5.6 Viewing Resources with Device Manager

This discussion applies equally to Windows 95/98/ME and 2000/XP. Windows maintains a registry of all known hardware installed within the computer. Inside this hardware registry Windows keeps track of all the computer's resources, such as base I/O addresses, IRQ levels, and DMA channels. In the case of a PCI plug-in card, Windows configures the new hardware using free resources it finds within the hardware registry, and updates the registry automatically.

To view and/or edit hardware devices in Windows use the system Device Manager. Consult Windows on-line help for details on the use of the Device Manager.

The following instructions provide step-by-step instructions on viewing resources used by the DSC-200/300 in Windows using the "Device Manager" utility. Select StartHelp from within Windows for additional information on this utility.

1.Double click the "System" icon inside the Control Panel folder. This opens up the System Properties box.

2.Click the "Device Manager" tab located along the top of the System Properties box. This lists all hardware devices registered inside the Windows registry. Additional information is available on any of these devices by right-clicking on the device name and then selecting "Properties" from the pop-up menu.
