Support Note:
We recommend you make a backup of important information
on your system's hard drive(s) prior to installing new hardware or software. When
handling computer products, you must take care to prevent components from being dam-
aged by static electricity. Always ground yourself by touching a grounded metal part of the
computer such as the power supply's metal case and work in an area free of static electricity;
avoid carpeted areas. Handle the Crescendo/7200 only by its edges and avoid touching
connector traces, component pins on PCI cards and other components inside the computer.
WARNING—You must install the Crescendo/7200 Software before
installing the Crescendo/7200 card!
