The branded Intel® Desktop Boards listed below do not include an onboard ATAPI CD-ROM connector. These boards include a digital audio solution which does not require an additional cable connection between the CD-ROM drive and the onboard ATAPI CD-ROM connector.

To enable digital audio, your CD-ROM/DVD drive must support digital audio and must be enabled for it. Check the properties of your CD-ROM/DVD drive in Device Manager .
