Found New Hardware Wizard. Please select Search for the best driver for my
devices (Recommend) and click Next.
2. Insert the Drivers CD into your CDROM/DVDROM drive, and select Install from a
list or specific location (Advanced), enter d:\ in the text box provided, and click

WARNING! PCI Express cards, like all computer equipment, can be severely
damaged by static electricity. Be sure that you are properly grounded before
opening your computer case or touching your card. StarTech.com recommends
that you wear an anti-static strap when installing any computer component. If
an anti-static strap is unavailable, discharge yourself of any static electricity
build-up by touching a large grounded metal surface (such as the computer
case) for several seconds. Also be careful to handle the card by its edges and
not the gold connectors.
