TCO Legacy/Compatible Mode SMBus Configuration
In TCO Legacy/Compatible mode the Intel ICH8/ICH8M can function directly with the
integrated Gigabit Ethernet controller or equivalent external LAN controller to report
messages to a network management console without the aid of the system processor.
This is crucial in cases where the processor is malfunctioning or cannot function due to
being in a low-power state.
to the network management console.
Event Transitions that Cause Messages
NOTE: The GPIO11/SMBALERT# pin will trigger an event message (when enabled by the
INTRUDER# pin
THRM# pin
Watchdog Timer

SMBALERT# pin
BATLOW#
CPU_PWR_FLR
GPIO11_ALERT_DISABLE bit) regardless of whether it is configured as a GPI or not.

that the THRM# pin is isolated when
the core power is off, thus preventing
this event in S3-S5.
