Desktop Board Features 
 
 
17 
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.
