Processor Core
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). Boards
equipped with the 2 x 4-pin processor core power connector will also include
heatsinks in the processor voltage regulator area.
• 2 x 2-pin
SCSI Hard Drive
LED Header
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
