Desktop Board Features Hi-Speed USB 2.0 Support The Desktop Board supports up to ten USB 2.0 ports (four ports routed to the back panel and six ports routed to three internal headers). 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. Serial ATA Support The Desktop Board supports six SATA channels (3.0 Gb/s) including five internal and one external eSATA channel. Each channel can support one device. Expandability For system expansion, the Desktop Board provides the following expansion connectors: • One PCI Express 2.0 x16 connector • One PCI Express 1.1 x1 connector • Two PCI bus connectors BIOS The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI/PCI Express auto-configuration utilities, and the video BIOS. The BIOS is stored in the Serial Peripheral Interface (SPI) Flash device. The BIOS can be updated by following the instructions in Chapter 3. ATA Auto Configuration If you install an ATA device (such as a hard drive) in your computer, the autoconfiguration utility in the BIOS automatically detects and configures the device for your computer. You do not need to run the BIOS Setup program after installing an ATA device. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program. 21

•
One PCI Express 1.1 x1 connector
•
Two PCI bus connectors
BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the
PCI/PCI Express auto-configuration utilities, and the video BIOS.
The BIOS is stored in
the Serial Peripheral Interface (SPI) Flash device.
