Table 2 describes the manufacturing options.  Not every manufacturing option is available in all 
marketing channels.  Please contact your Intel representative to determine which manufacturing 
options are available to you. 

Provides required additional power when using high power (75 W or greater) add-in 
cards in either or both the Secondary PCI Express x16 (electrical x8) and the PCI 
Express x16 (electrical x4) bus add-in card connectors 

A 1 x 4-pin ATAPI-style connector for connecting an internal ATAPI CD-ROM drive to 
the audio mixer 

Intel High Definition Audio subsystem in one of the following configurations: 
•  8-channel (7.1) audio subsystem with five analog audio outputs and two S/PDIF 

digital audio outputs (coaxial and optical) using the Sigmatel* 9221 audio codec 

•  6-channel (5.1) audio subsystem with three analog audio outputs using the 

Sigmatel 9220 audio codec 

•  Silicon Image Sil 3114 SATA RAID controller 
•  Four SATA connectors (in addition to the four SATA connectors on the 

ICH7-R/ICH7-DH SATA interface) 

IEEE-1394a controller and two IEEE-1394a connectors:  one back panel connector 
and one front-panel connector 

One of the following connectors for providing +12 V power to the processor voltage 
regulator: 
•  2 x 4-pin (requires a power supply with a dual-rail 2 x 4 power cable).  Boards 

equipped with the 2 x 4-pin processor power connector will also include heatsinks 
in the processor voltage regulator area. 

•  2 x 2-pin 

Allows add-in hard drive controllers (SCSI or other) to use the same LED as the 
onboard IDE controller. 

A component that enhances platform security
