5.4 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 DSC-100 to allow easy configuration in
the Windows 95 environment. Also a custom Windows 95 serial device driver is included with
the DSC-100 to support the use of the 16550 UART's 16 byte FIFO. Windows 95 uses the "INF"
file to determine the system resources required by the DSC-100, searches for available resources
to fill the boards requirements, and then updates the hardware registry with an entry that allocates
these resources.
5.5 Using the "New Hardware Found" Wizard
The following instructions provide step-by-step instructions on installing the DSC-100 in
Windows 95 using the "New Hardware Found" wizard.
1. After booting the computer with a newly-installed DSC-100, 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 disk 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 disk. 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 disk. 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 disk.
8. The installation utility will ask for your Windows 95 installation disks. Serial
communication ports require two drivers supplied by Microsoft to function:
