Intel DP45SG 用户手册

The Desktop Board supports up to 12 USB 2.0 ports (six ports routed to back panel 
connectors and six ports routed to three onboard headers) via the ICH10R.  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. 

Intel Desktop Board DP45SG supports five onboard Serial ATA channels and one 
eSATA channel (3.0 Gb/s) via ICH10R. 

The five onboard Serial ATA channels support the following RAID (Redundant Array of 
Independent Drives) levels via Intel Matrix Storage Technology: 
•  RAID 0 - data striping 
•  RAID 1 - data mirroring 
•  RAID 0+1 (or RAID 10) - data striping and data mirroring 
•  RAID 5 - distributed parity 
For information on configuring your system for RAID using Intel Matrix Storage 
Technology go to Chapter 4. 

The Desktop Board supports Intel Rapid Recover Technology which enables fast and 
easy recovery of your data in the event of a hard drive failure.  It allows you to 
maintain a complete copy of your primary or master drive onto a second hard drive, 
the recovery drive.  If the master hard drive should fail, either from a mechanical 
failure or the result of a virus, recovery is as simple as booting from the recovery 
drive.  The recovery drive can be attached to your system via any standard SATA or 
eSATA connection.  

Intel Rapid Recover Technology also provides the added benefit of allowing the 
recovery drive to be mounted as a read-only volume so you can quickly copy files from 
the recovery drive when individual files need to be recovered. 

For information on configuring your system for Intel Rapid Recover Technology see 
Chapter 5.
