If you don't know the manufacturer of your Cirrus- or Crystal-based product (Crystal Semiconductor was purchased by Cirrus Logic in 1991), you can locate your manufacturer through the Federal Communication Commission (FCC) number, which should be printed on the card itself. This number will appear with FCC ID and the # sign followed by a 17-digit number. The first three characters are all that you need to find your manufacturer; search the FCC database at www.fcc.gov/oet/fccid/.

As a convenience to you, we offer an archive of all our available generic audio and Ethernet drivers at www.cirrus.com/en/support/drivers/index.html. We do not provide end-user driver support, and we do not take responsibility for the performance of any drivers, which may have been modified for individual products by the product manufacturer.

Our line of modem products is now owned and supported by Intel. Please contact them at www.intel.com if you need drivers or support for a modem product.

The company that owned our graphics technology (ISDCorp) is no longer in the graphics business. If you need graphics drivers, www.video-drivers.com has some drivers for our old graphics chips.

If you are seeking Windows-based audio drivers, visit the Microsoft Web site (www.microsoft.com) and do a Search. In many cases, the drivers are available on this Web site.

If none of the above addresses your needs, you might try www.driverguide.com; they have many Cirrus Logic drivers listed.
