ICH8 Family Datasheet
Advanced TCO Mode
Intel ICH8/ICH8M supports two modes of Advanced TCO. Intel
Technology mode and BMC mode. To enable Advance TCO mode (AMT or BMC mode)
the TCOMODE bit 7 in the ICHSTRP0 register in the SPI device must be 1. See
Section 20.2.5.1
Advanced TCO Intel® Active Management Technology mode
In this mode, Intel AMT SMBus Controller 1, Host SMBus and SMLink are connected
together internally. See Figure below. This mode is enabled when the BMCMODE bit 15
in the ICHSTRP0 register in the SPI device is 0. See
The Intel AMT 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. See
Section 20.2.5.1
connected to SMLink. The AMT SMBus Controller 2 has no connection to LINKALERT#.
Advanced TCO Intel® AMT Mode SMBus/SMLink Configuration
Advanced TCO BMC Mode
In this mode, the external microcontroller (BMC) is connected to both SMLink and
SMBus. The BMC communicates with Management Engine through AMT SMBus
connected to SMLink. The host and TCO slave communicated with BMC through SMBus.
See figure below. This mode is enabled when the BMCMODE bit 15 in the ICHSTRP0
register in the SPI device is 1. See
