4.4 Windows 1995
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(LP)-200/300 to allow easy
configuration in the Windows 95 environment. Also a custom Windows 95 serial device driver is
included with the QSC(LP)-200/300 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(LP)-200/300, searches for available resources to fill the boards requirements, and then
updates the hardware registry with an entry that allocates these resources
The following instructions provide step-by-step instructions on installing the
QSC(LP)-200/300 in Windows 95 using the "New Hardware Found" wizard.
1. After booting the computer with a newly-installed QSC(LP)-200/300, the "New
Hardware Found" dialog box will appear. If you have never installed a Quatech PCI
communications adapter before, the dialog box may simply indicate that it has found a
"PCI Card."
2. Select the radio button for "Driver from disk provided by hardware manufacturer." Click
the "OK" button to continue.
3. An "Install From Disk" dialog box should pop up. Insert the cd with the Quatech INF files
on it, select the correct drive letter, and click the "OK" button. Windows 95 automatically
browses the root directory for an INF file that defines configurations for Multi-function
Adapters. If no INF files are found, click the "Browse" button and search the Win95 sub
directory on the installation cd. 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 CD provided by hardware manufacturer."
Click the "OK" button to continue.
6. Another "Install From CD" 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 CD.
8. The installation utility will ask for your Windows 95 installation disks. Serial
communication ports require two drivers supplied by Microsoft to function:
SERIAL.VXD and SERIALUI.DLL. Insert the disk or CD and click "OK".
