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.
