Resumen del manual
NOTES Computer systems that have an unshielded cable attached to a USB port may not meet FCC Class B requirements, even if no device is attached to the cable. Use a shielded cable that meets the requirements for full-speed devices. For information about Refer to The location of the USB connectors on the back panel Figure 9, page 46 The location of the front panel USB headers Figure 10, page 47 Intel Desktop Board DQ67OW Technical Product Specification 1.9 SATA Interfaces The board provides six SATA connectors through the PCH, which support one device per connector: • Two internal SATA 6 Gb/s ports (blue) • Two internal SATA 3 Gb/s ports (black) • Two internal eSATA 3 Gb/s ports for external connectivity (red) The PCH provides independent SATA ports with a theoretical maximum transfer rate of 6 Gb/s for two ports and 3 Gb/s for four ports. A point-to-point interface is used for host to device connections. The underlying SATA functionality is transparent to the operating system. The SATA controller can operate in both legacy and native modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI Conventional bus resource steering is used. Native mode is the preferred mode for configurations using the Windows* XP, Windows Vista*, and Windows 7* operating systems. For more information, see: For information about Refer to The location of the SATA connectors Figure 10, page 47 1.9.1.1 Serial ATA RAID The board supports the Intel Rapid Storage Technology (Intel RST) which provides 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 NOTE In order to use supported RAID features, you must first enable RAID in the BIOS. Also, during Microsoft Windows XP installation, you must press F6 to install the RAID drivers. See your Microsoft Windows XP documentation for more information about installing drivers during installation. Both Microsoft Windows Vista and Microsoft Windows 7 include the necessary RAID drivers for both AHCI and RAID without the need to install separate RAID drivers using the F6 switch in the operating system installation process. Product Description 1.9.1.2 Intel® Rapid Recover Technology The board incorporates the Intel® Rapid Recover Technology (Intel® RRT). Intel Rapid Recover Technology is a feature of Intel Rapid Storage Technology. It uses RAID 1 (mirroring) functionality to copy data from a designated master drive to a designated recovery drive. The master drive data can be copied to the recovery drive either continuously or on request. When using the continuous update policy, changes made to the data on the master drive while the recovery drive is disconnected or offline are automatically copied to the recovery drive when it is reconnected. When using the on request update policy, the master drive data can be restored to a previous state by copying the data on the recovery drive back to the master drive. For information about Refer to Intel Rapid Recovery Technology imsm/sb/CS-026142.htm 1.10 Legacy I/O Controller The Legacy I/O Controller provides the following features: • One serial port • One back panel parallel port (with Extended Capabilities Port (ECP) and Enhanced Parallel Port (EPP) support • One diskette drive connector • PS/2-style keyboard/mouse interface on the back panel • Serial IRQ interface compatible with serialized IRQ support for PCI Conventional bus systems • Intelligent power management, including a programmable wake-up event interface • PCI Conventional bus power management support The BIOS Setup program provides configuration options for the Legacy I/O controller. 1.10.1 Serial Port The serial port is implemented as a 10-pin header on the board. The serial port supports data transfers at speeds up to 115.2 kbits/s with BIOS support. For information about Refer to The location of the serial port header Figure 10, page 47 Intel Desktop Board DQ67OW Technical Product Specification 1.11 Audio Subsystem The board supports Intel High Definition Audio through the Realtek ALC888S audio codec interface. The Realtek ALC888S-based audio subsystem supports the following features: • 8-channel audio with independent multi-streaming stereo. • Advanced jack sense for the back panel audio jacks that enables the audio codec to recognize the device that is connected to an audio port. The back panel audio jacks are capable of retasking according to the user’s definition, or can be automatically switched depending on the recognized device type. • Stereo input and output through back panel jacks • Headphone and Mic in functions for front panel audio jacks • S/PDIF audio header • A signal-to-noise (S/N) ratio of 90 dB 1.11.1 Audio Subsystem Software Audio software and drivers are available from Intel’s World Wide Web site.
