Components
Q45 GMCH
82801 ICH10-DO
The I/O controller hub (ICH10-DO) supports Intel vPro, which uses 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
