USB 2.0 Support

The Desktop Board supports up to seven USB 2.0 ports (four ports routed to the back panel and three ports routed to two front panel USB 2.0 headers). One of the front panel USB headers supports an Intel Z-U130 USB Solid-State Drive (or compatible device). The USB 2.0 ports are 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 High-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.

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.

SATA Interface

The Desktop Board supports two SATA channels (3.0 Gb/s) that support one device per channel. The SATA controller supports IDE and ACHI configuration and can operate in both legacy and native modes.

Expandability

The Desktop Board provides the following expansion capability:

•One PCI connector. The connector can support either a single PCI add-in card or a single- or dual-slot PCI riser card.

•One PCI Express Full-Mini Card slot.
