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.
