The SPI Flash Memory device is an Atmel AT26DF321*, 32-mbit, 2.7 to 3.6 V serial interface
FLASH memory, Intel part number D64145-001/D64145-002. The AT26DF321 supports the
block erase command opcodes 20H and D8H, providing, respectively, 4-Kbytes or 64-Kbytes
block erase sizes. It installs directly onto the server board without the use of sockets.
3.2.3.15 Manageability
®
The Intel ICH9 integrates several functions designed to manage the system and lower the total
cost of ownership (TCO) of the system. These system management functions are designed to
report errors, diagnose the system, and help the system recover from lockups without the aid of
an external microcontroller.
The management engine includes the following features:
A TCO Timer used to detect system locks
A Process Present Indicator that can determine if the processor fetches the first
instruction after reset
ECC Error reporting from the host controller
A Function Disable option to prevent disabled functions from generating interrupts and
power management events
An Intruder Detect input for system cases
