Desktop Board Features Enhanced IDE Interface The ICH7R's IDE interface handles the exchange of information between the processor and peripheral devices like hard disks, CD-ROM drives, and Iomega Zip* drives inside the computer. The interface supports: • Up to two IDE devices (such as hard drives) • ATAPI-style devices (such as CD-ROM drives) • Older PIO Mode devices • Ultra DMA-33 and ATA-66/100 protocols • Laser Servo (LS-120) drives Serial ATA The desktop board supports eight Serial ATA channels via the ICH7R, connecting one device per channel in either a RAID or non-RAID configuration. Expandability The desktop board supports the following: • One PCI Express x16 add-in card • One PCI Express x4 add-in card (routed to the physical x16 connector) • One PCI Express x1 add-in card • Three PCI bus add-in cards Related Links For information about installing the PCI Express x16 card, see page 36 in Chapter 2. 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. See Chapter 3 on page 59 for more information about the BIOS. Serial ATA and IDE Auto Configuration If you install a Serial ATA or IDE device (such as a hard drive) in your desktop board, the autoconfiguration utility in the BIOS automatically detects and configures the device for your computer. You do not need to run the BIOS Setup program after installing a Serial ATA or IDE device. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program. When booting from a Serial ATA device, Serial ATA connector 0 is the first boot device and Serial ATA connector 3 is the last boot device by default. 17
