QuickPlay is a technology pioneere by Hewlett-Packard currently used in their Pavilion line of consumer entertainment notebook computers beginning with the dv1000 series and above, including the new Pavilion HDX series. This feature allows users to play their music CDs, DVD movies, and MP3s stored on the hard drive in a separate Linux partition without booting to the main operating system. The last revision of QuickPlay "Direct" 2.3 uses Windows XP Embedded instead of Linux. This technology has been expanded to include the Compaq v3000 and many other Compaq notebook models, and has also been emmulated by other computer manufacturers such as Dell, Alienware, and Toshiba in their own notebook product lines.
