Appendix A: Glossary
Term
Definition
ACPI Advanced
Configuration and Power Interface.
ANSI American
National
Standards Institute.
ASCII
American Standard Code for Information Interchange. An 8-level code (7 bits plus parity check)
widely used in data processing and data communications systems.
ASIC Application
specific integrated circuit.
BERR
Bus Error Signal. This signal can be driven by the platform to interrupt the processor that a
platform MCA condition occurred. The processor does not reset any internal state when it sees a
BERR condition. The signal causes a global MCA condition. For further information, see the
Itanium™ Processor Family Error Handling Guide.
BINIT
Bus Initialization Signal. This signal can be driven by the processor or platform to indicate a fatal
machine check condition. The processor and platform will reset internal state in order to ensure
the firmware code can be fetched and executed. This signal causes a global MCA condition. For
further information, see the Itanium™ Processor Family Error Handling Guide.
BIOS
Basic Input Output System.
BIST
Built-In Self Test.
BMC
Baseboard Management Controller.
Bridge
Circuitry connecting one computer bus to another, allowing an agent on one to access the other.
BSP
Boot Strap Processor.
byte 8-bit
quantity.
CBC
Chassis Bridge Controller. A microcontroller connected to one or more other CBCs. Together they
bridge the IPMB buses of multiple chassis.
CHAP
Challenge Handshake Authentication Protocol.
CHS
Cylinder- Head-Sector. An older addressing scheme for accessing physical sectors on hard drives
and other storage devices. See LBA.
CMCI
Corrected Machine Check Interrupt.
CMOS
In terms of this specification, this describes the PC-AT compatible region of battery-backed 128
bytes of memory, which normally resides on the baseboard.
CPEI Corrected
Platform Event Interrupt.
CVDR
Configuration Values Driven on Reset. A register in the chipset that is accessible by the BMC to
control certain system parameters.
DFT
Design for Test. DFT is a set of design rules whose purpose is to improve platform and system
testability.
DMA
Direct Memory Access.
DSDT
Differentiated System Description Table. An OEM must supply a DSDT to an ACPI-compatible
OS. The DSDT contains the Differentiating Definition Block, which supplies the implementation
and configuration information about the base system.
DTLB
Distributed Translation Lookaside Buffer.
DWORD
Double Word, a 32-bit quantity.
EEPROM
Electrically erasable programmable read-only memory.
ECC
Error Correction Code. Refers to a memory system that has extra bit(s) to support limited
detection/correction of memory errors.
EMP
Emergency Management Port.
EPS
External Product Specification.
FRB
Fault Resilient Booting.
FRU
Field Replaceable Unit.
