Table 2.  Manufacturing Options 
Alternate (ALT) 
Power Input 
Connector 
Provides required additional power when using high power (75 W or greater) add-in 
cards in both the PCI Express x16 and the Secondary PCI Express x16/x4 bus add-in 
card connectors 
ATAPI CD-ROM 
connector 
A 1 x 4-pin ATAPI-style connector for connecting an internal ATAPI CD-ROM drive to 
the audio mixer 
Audio Subsystem 
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 
Auxiliary (AUX) 
Power Output 
Connector 
Provides power for internal chassis lighting 
Discrete SATA 
RAID controller 
•  Silicon Image Sil 3114 SATA RAID controller 
•  Four SATA connectors (in addition to the four SATA connectors on the ICH7-R 
SATA interface) 
IEEE-1394a/b 
Interface 
IEEE-1394a/b controller and three IEEE-1394a/b connectors:  one back panel 
connector, two front-panel connectors.  Back panel connector is IEEE-1394a-
compatible only; front panel connectors are 1394a- or 1394b-compatible, configurable 
through the BIOS Setup program.   
Processor power 
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) 
•  2 x 2-pin 
SCSI Hard Drive 
Activity LED 
Connector 
Allows add-in hard drive controllers (SCSI or other) to use the same LED as the 
onboard IDE controller. 
Trusted Platform 
Module (TPM) 
A component that enhances platform security
