Functional Description
5.14.2.2.1
Advanced TCO Intel® Manageability Engine Mode
In this mode, Intel ME SMBus Controller 1, Host SMBus and SMLink are connected
together internally. See Figure 5-7. This mode is enabled when the BMCMODE bit 15 in
the ICHSTRP0 register in the SPI device is 0.
The Intel ME SMBus Controller 2 can be connected to either the SMBus pins or the
SMLink pins by the MESM2SEL bit 23 in the ICHSTRP0 register in the SPI device. The
default is to have the Intel ME SMBus Controller 2 connected to SMLink. The Intel ME
SMBus Controller 2 has no connection to LINKALERT#.
