To successfully find the correct driver for any hardware item (card) the card type must be known. If the card type is not knows there are several ways that it can be determined. One way is to go to this URL:
http://www3.compaq.com/support/parts/
Use the AutoDetect button and see if your EN model can be identified. If it is identified then a list of cards should be shown. This card type can then be used to select the correct drivers at the driver link below.
Another way is to run the Compaq diagnostic for Windows from Control Panel. The card type will be identified there.
Or the F10 Computer Diagnostics Inspect utility can be run to identify the card.
