Desktop Board Features

USB 2.0 Support

The Desktop Board supports up to eight USB 2.0 ports (four ports routed to the back

panel and four ports routed to two front panel USB 2.0 headers). 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

For system expansion, the Desktop Board provides one PCI connector that can support

either a single PCI add-in card or a single- or dual-slot PCI riser card.

BIOS

The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI

and SATA auto-configuration utilities, and the video BIOS.

PCI Auto Configuration

If you install a PCI add-in card in your computer, the PCI auto-configuration utility in

the BIOS automatically detects and configures the resources (IRQs, DMA channels,

and I/O space) for that add-in card. You do not need to run the BIOS Setup program

after you install a PCI add-in card.
