Intel DQ35MP manual Hi-Speed USB 2.0 Support, Enhanced IDE Interface, Serial ATA RAID

Desktop Board Features

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 ICH9DO. 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 ICH9DO, connecting one device per channel. One channel is configured as an eSATA channel.

Serial ATA RAID

The ICH9DO supports the following RAID (Redundant Array of Independent Drives) levels:

•RAID 0 - data striping

•RAID 1 - data mirroring

•RAID 0+1 (or RAID 10) - data striping and mirroring

•RAID 5 - distributed parity

For information on configuring your system for RAID using Intel® Matrix Storage Technology see Chapter 4.
