Desktop Board Features
21
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 auto-
configuration 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.
