Desktop Board Features AGP Connector ✏ NOTE The boards are compatible with 1.5 V AGP cards only. AGP is a high-performance interface for graphics-intensive applications such as 3D graphics. AGP is independent of the PCI bus and is intended for use with graphical display devices. The AGP connector supports 1.5 V AGP 4X and 2X add-in cards. An AGP card retention mechanism (RM) may be included with the boxed desktop board to be used only with cards with retention notches (see Figure 14 on page 32). For information about installing the AGP card RM and an AGP card, see Chapter 2 on page 21. Communication and Networking Riser (CNR) (Optional) The CNR provides an interface that supports various features such as audio, modem, USB, and LAN interfaces of the Intel 850 chipset. Audio Subsystem The AC '97 compliant audio subsystem consists of the following: • Intel 82801BA I/O Controller Hub (ICH2) • Analog Devices Inc. AD1885 analog codec ✏ NOTE The audio line out connector, located on the back panel, is designed to power either headphones or amplified speakers only. Poor audio quality may occur if passive (non-amplified) speakers are connected to this output. Audio drivers and utilities are available from Intel's World Wide Web site: http://support.intel.com/support/motherboards/desktop BIOS The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI and IDE auto-configuration utilities, and the video BIOS. The BIOS is stored in the Firmware Hub. The BIOS can be updated by following the instructions in Chapter 3 on page 43. PCI Auto Configuration If you install a PCI add-in card in your computer, the PCI auto-configuration utility in the BIOS automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that add-in card. You do not need to run the BIOS Setup program after you install a PCI add-in card. 15
