Hi-Speed USB 2.0 Support

The Desktop Board supports up to 12 USB 2.0 ports (six ports routed to the back
panel and six ports routed to three internal headers) via ICH10. 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.

Enhanced IDE Interface

The board's IDE interface handles the exchange of information between the processor
and peripheral devices such as hard disk drives and CD-ROM drives. The interface
supports:
• Up to two IDE devices (such as hard drives)
• ATAPI-style devices (such as CD-ROM drives)
• Older PIO Mode devices
• Ultra DMA-33 and ATA-66/100 protocols

Serial ATA

The Desktop Board supports six Serial ATA channels (3.0 Gb/s) via ICH10, connecting
one device per channel.

Expandability

For system expansion, the Desktop Board provides the following expansion slots:
• One PCI Express 2.0 x16 connector (also compatible with PCI Express 1.1 add-in
cards)
• Three PCI Express 1.1 x1 connectors
• Three PCI bus connectors
