7.2 Driver Installation
7.2.1 Before you begin
Before you begin installing software drivers, you should make a
backup copy of the display driver disk and store the original in a safe
place. The display driver disk contains drivers for several versions of
certain applications. You must install the correct version in order for
the driver to work properly, so make sure you know which version of
the application you have.
