Integrated Baseboard Management Controller; Functionality Overview - Intel X38ML - Server Board Motherboard Technical Manual

Functional Architecture
The SPI Flash Memory device is an Atmel* AT26DF321 - a 32 mbit, 2.7 to 3.6 volt serial
interface FLASH memory, Intel part number D64145-001/D64145-002. This device is installed
directly onto the server board without the use of sockets.
3.2.2.12 Manageability
®
The Intel ICH9 integrates several functions to manage the system and lower the total cost of
ownership (TCO) of the system. These system management functions report errors, diagnose
the system, and recover from system lockups without the aid of an external microcontroller.
The management engine includes the following features:
TCO timer to detect system locks
Process Present Indicator to determine if the processor fetches the first instruction after
reset
ECC Error reporting from the host controller
Function Disable to prevent a disabled function from generating interrupts and power
management events
Intruder Detect input for system cases

Integrated Baseboard Management Controller

A ServerEngines* Baseboard Management Controller (Integrated BMC) is integrated onto the
server board. This integrates the baseboard management controller (BMC and KVMS
subsystem), graphics controller (graphics subsystem), and Super I/O interface (Super I/O
subsystem). The Intel
