3.2 DSP-100 Resource Settings in Windows 95
Windows 95 maintains a registry of all known hardware installed within the computer.
Inside this hardware registry Windows 95 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 95 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 95 use the system Device
Manager. To access Device Manager double click the System icon in the Windows 95
control panel, or click the My Computer icon on the Win95 desktop with the right
mouse button and select Properties from the pull down menu. Consult Windows 95
on-line help for details on the use of the Device Manager.
