	SDRAM controller supporting unbuffered, non-ECC PC2-6400 DDR2
	DIMMs or SODIMMs
	800-, 1066-, or 1333-MHz FSB
82801 ICH9-DO	PCI 2.3 bus I/F
	PCI Express x1
	LPC bus I/F
	SMBus I/F
	SATA I/F
	HD audio interface
	RTC/CMOS
	IRQ controller
	Power management logic
	USB 1.1/2.0 controllers supporting 12 ports
	(these systems provide 8 external, 2 internal)
	Gigabit Ethernet controller

The I/O controller hub (ICH9-DO) features Intel vPro, which includes Active Management Technology (AMT). AMT is a hardware/firmware solution that operates on auxiliary power to allow 24/7 support of network alerting and management of the unit without regard to the power state or operating system. AMT capabilities include:

■System asset recovery (hardware and software configuration data)

■OS-independent system wellness and healing

■Software (virus) protection/management
