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.
