This package provides the drivers for the Realtek AC97 High Defintion (HD) Audio in the listed desktop models and operating systems. NOTE - Users creating their own disk images must first install the Microsoft Universal Audio Architecture (UAA) driver before installing the Realtek driver. The Microsoft UAA driver provides the necessary support for the HD audio bus used by the Realtek HD audio CODEC. Users who are upgrading to this newer driver on an existing system, should ensure that the Microsoft UAA driver is already installed on the system. The Microsoft UAA driver may be listed on the system as the "High Definition Audio Driver Package." There are separate Microsoft UAA drivers for different versions of the operating system. For example, Microsoft Windows XP with Service Pack 1 and Microsoft Windows XP with Service Pack 2 Operating Systems each have a different UAA driver.
