LAN Connector LEDs LED A (Link) B (Speed) LED Color Green N/A Green Yellow LED State Off On Blinking Off On On Indicates LAN link is not established LAN link is established LAN activity is occurring 10 Mb/s data rate 100 Mb/s data rate 1000 Mb/s data rate Hi-Speed USB 2.0 Support The Desktop Board supports up to 10 USB 2.0 ports (six ports routed to the back panel and four ports routed to two internal headers) via ICH8. 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 board's IDE interface handles the exchange of information between the processor and peripheral devices such as hard disk drives and CD-ROM drives. 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 Serial ATA The Desktop Board supports four Serial ATA channels (3.0 Gb/s) via ICH8, connecting one device per channel. 17
