Introduction
programmed during the manufacturing and is write-protected. See
Section 6.4 for details on
the PIROM.
Retention mechanism - The support components that are mounted through the baseboard to
the chassis to provide mechanical retention for the processor and heatsink assembly.
Scratch EEPROM (Electrically Erasable, Programmable Read-Only Memory) - A
memory device located on the Intel Xeon processor MP with up to 2-MB L3 cache processor
and the Intel Xeon processor in INT-mPGA package, addressable via the SMBus which can be
used by the OEM to store information (e.g., information for system management, etc). See
SMBus - System Management Bus. A two-wire interface through which simple system and
power management related devices can communicate with the rest of the system. It is based on
the principals of the operation of the I2C two-wire serial bus from Philips Semiconductor.
