Word / Acronym Definition
16-bit Legacy The traditional personal computer environment. Includes legacy Option ROMs and
legacy 16-bit code.
ACPI Advanced Configuration and Power Interface. ACPI is an open industry
specification proposed by Intel, Microsoft and Toshiba. ACPI enables and supports
reliable power management through improved hardware and operating system
coordination. For more information, see ACPI_1.0b or ACPI_2.0.

ASL ACPI Source Language
ASR Asynchronous System Reset.
Asserted Active-high (positive true) signals are asserted when in the high electrical state
(near power potential). Active-low (negative true) signals are asserted when in the
low electrical state (near ground potential).
Asynchronous An event that causes a change in state with no timing relationship to a particular
timing reference (such as a clock signal).
BAR Base Address Register. Device configuration registers that define the start
address, length and type of memory space required by a device.

BEV BootStrap Entry Vector.
BIOS Basic Input/Output System. The firmware (Software embedded into hardware) that
is used to boot the processors and initialize the chipset and I/O of the system prior
to handing off control of execution to the operating system.
BIST Built-in self test
BMC Baseboard Management Controller. A management microcontroller on the
baseboard that is used for voltage, temperature, and fan failure sensing. The
device also serves as an I2C Master controller, and as the system's Event
Receiver.
Bridge Circuitry connecting one computer bus to another, allowing an agent on one to
access the other.
BSP Boot Strap Processor. The processor selected at boot time to be the primary
processor in a multi-processor system.
