Desktop Board Features Hi-Speed USB 2.0 Support NOTE Computer systems that have an unshielded cable attached to a USB port might not meet FCC Class B requirements, even if no device or a low-speed USB device is attached to the cable. Use a shielded cable that meets the requirements for a full-speed USB device. The Desktop Board supports up to six USB 2.0 ports (two ports routed to the back panel and four ports routed to two internal USB 2.0 headers). The USB 2.0 ports are backward compatible with USB 1.1 devices. USB 1.1 devices will function normally at USB 1.1 speeds. USB 2.0 support requires both an operating system and drivers that fully support USB 2.0 transfer rates. Disabling Hi-Speed USB in the BIOS reverts all USB 2.0 ports to USB 1.1 operation. This may be required to accommodate operating systems that do not support USB 2.0. Enhanced IDE Interface The IDE interface handles the exchange of information between the processor and peripheral devices such as hard disks and optical drives inside the computer. The interface supports: • Up to two IDE devices (such as hard drives) • ATAPI-style devices (such as CD-ROM or DVD drives) • Older PIO Mode devices • Ultra DMA-33/66/100 modes Expandability The Desktop Board supports one PCI add-in card. 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. IDE Auto Configuration If you install an IDE device (such as a hard drive) in your computer, 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 an IDE device. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program. 17
