Determining Your Version of

Windows 95

There are different versions of Windows 95 on the market. One of the primary ways these versions differ is in the way they handle the addition of new hardware. Follow these steps to determine your version of Windows 95. This information will be important during installation.

1.Click the My Computer icon on your desktop with the right mouse button.



blank below for future reference. Then click OK.

Windows 95 version _________________

3.In the “System Properties” screen, look at the system information under the General tab (circled in the following screen image). The number following the text “Microsoft Windows 95” will end with “950”, “950a”, or “950b”. This indicates your version of Windows 95. Write this number on the



Inserting the Video Capture

Card into Your Computer

NOTE: Before installing your capture card, write down the card’s serial number in this space:


You will find the serial number underneath the bar code on the white sticker on the capture card and on your Bigpicture package. If you ever need to call our technical support department, the technical support representative will ask you for this serial number. This number will help him or her identify your capture card.

Your video capture card supports Plug and Play installation, the fastest, easiest way to add new hardware to your PC. Windows 95 should do all the work of detecting your new hardware.

TIP: Before you unplug anything, label the cords or make a sketch of how things are connected. This can be helpful when you plug things back in later.

1.Turn off your computer and unplug it from the electrical outlet.

2.Unplug any peripheral devices (printer, monitor, keyboard, mouse, etc.) from the computer.



CAUTION : To avoid risk of electric shock, make sure your computer and all peripheral devices are turned off and unplugged from electrical outlets.

3.Remove the screws from your computer’s cover and then remove the cover. Your computer may not resemble the computer in the following diagrams, but the basic principle for removing the cover should be the same. Refer to your computer’s documentation if you need further instructions.

4.Touch an unpainted metal part of your computer (the back panel, for example) to discharge any static electricity you may be carrying. Static electricity can damage electronic components.



5.There should be two types of expansion slot inside your computer, ISA and PCI (see the following diagrams). Find an empty PCI slot inside your computer. PCI slots are usually white plastic grooves lined with silver metal. ISA slots are usually longer black plastic grooves lined with silver metal.




6.Unscrew and remove the expansion slot cover (the long, narrow piece of metal that keeps dust from entering through the opening perpendicular to the slot). Be careful not to drop the screw into the PC.

7.Holding the video capture card at each corner, with the gold edge facing the slot, push the card down as gently as possible until it snaps into the expansion slot. You

will need to apply some pressure to properly fit the capture card into the expansion slot. A gentle back-and-forthmotion helps seat the card all the way into the slot. If you feel resistance, do not force the card into the slot. The card may not be properly aligned with the slot. Remove the card completely and try again.
