O compliant-I/O Platforms. These typically contain an I/O processor and I/O subsystem.
IP Internet Protocol.
IPMB Intelligent Platform Management Bus. Name for the architecture, protocol, and implementation of
a special bus that interconnects the baseboard and chassis electronics and provides a
communications media for system platform management information.
IPMI Intelligent Platform Management Interface. An industry standard that defines standardized,
abstracted interfaces to platform management hardware.
ISM Intel

Server Management.
IR Infrared.
ITP In-Target Probe.
KB Kilobyte=1024 bytes.
KCS Keyboard Controller Style.
LAN Local Area Network. A data communications system which allows a number of independent
devices to communicate with each other within a moderate size geographic area.
LBA Logical Block Address. An addressing scheme for accessing sectors on hard drives and other
storage devices. The LBA method is preferred over the CHS method (see CHS) because it can
address more sectors.
LPC Low Pin Count.
LUN Logical Unit Number.
MAC Media Access Control.

MD5 Message Digest 5 – Hashing Algorithm – Higher Security.
Ms Milliseconds.
MSB Most Significant Bit.
Mux Multiplexer.
NIC Network Interface Card.
NMI Non-maskable Interrupt. The highest priority interrupt in the system, after SMI. This interrupt has
traditionally been used to notify the operating system fatal system hardware error conditions, such
as parity errors and unrecoverable bus errors.
NVRAM Non-Volatile RAM.
OBF Output buffer.
OEM Original Equipment Manufacturer.
PAL Processor Abstraction Layer.
