4. Windows 95 Configuration
Windows 95 maintains a registry of all known hardware installed in your computer. Inside this
hardware registry Windows 95 keeps track of all of your system resources, such as I/O locations,
IRQ levels, and DMA channels. The "Add New Hardware Wizard" utility in Windows 95 was
designed to add new hardware and update this registry.
An “INF” configuration file is included with the DS-100 to allow easy configuration in the
Windows 95 environment . Also, a custom Windows 95 serial device driver is included with the
DS-100 to support the use of the FIFOs on the 16550 UARTs. Windows 95 uses the “INF” file
to determine the system resources required by the DS-100, searches for available resources to fill
the requirements of the board, and then updates the hardware registry with an entry that allocates
these resources.
Windows 95 will not automatically configure the DS-100. The user is required to manually
configure the hardware to match the resources that Windows 95 allocates to the DS-100.
Another option is to use the “Device Manager” in Windows 95 to change the system resources
allocated to match the configuration of the hardware. See section 3.2 for information on
changing resources within Windows 95.
