4.2 DSP-100 Resource Settings in Windows 98/ME
Windows 98/ME maintains a registry of all known hardware installed within the
computer. Inside this hardware registry Windows 98/ME keeps track of all the
computer's resources, such as base I/O addresses, IRQ levels, and DMA channels. In
the case of a PC Card (PCMCIA) type board, Windows 98/ME 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 98/ME use the system Device
Manager. To access Device Manager double click the System icon in the Windows
98/ME control panel, or click the My Computer icon on the Windows 98/ME
desktop with the right mouse button and select Properties from the pull down menu.
Consult Windows 98/ME on-line help for details on the use of the Device Manager.
