You are not required to select the file name. After finding the directory containing the INF files, Windows 95 will choose the correct file.

4.The "New Hardware Found" dialog box will appear again, this time for an "Unknown Device."

5.Again select the radio button for "Driver from disk provided by hardware manufacturer." Click the "OK" button to continue.

6.Another "Install From Disk" dialog box will pop up. The path should already be pointing to the Quatech CD. Click the "OK" button to continue.

7.You should now see the "Copying Files" dialog box as Windows 95 copies the driver files from the diskette.

8.The installation utility will ask for your Windows 95 installation CD. Serial communication ports require two drivers supplied by Microsoft to function: SERIAL.VXD and SERIALUI.DLL. Insert the disk or CD and click "OK".

NOTE:

You may be able to skip this step if you are certain that your system has the latest version of these files installed. If you do not have your Windows 95 install disks immediately available, click "OK" anyway. A dialog box appears with an option to Skip the files. Click the Skip button and the files will not be installed. This is all right if the latest version of these drivers are currently in the \WINDOWS\SYSTEM directory.

9.The "New Hardware Found" dialog will repeat for each of the serial ports on the QSC-100 as each port is registered with Windows 95.

10.Installation is complete.

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 QSC-100 to allow easy configuration in the Windows 95 environment. Also a custom Windows 95 serial device driver is included with the QSC-100 to support the use of the 16750 UART's 64 byte FIFO. Windows 95 uses the "INF" file to determine the system resources required by the QSC-100, searches for available resources to fill the boards requirements, and then updates the hardware registry with an entry that allocates these resources.
