Term Definition
BIOS Basic Input/Output System. The code that controls the server system startup process.
CMOS Complimentary Metal Oxide Semiconductor. Server system startup parameters are stored
in CMOS memory. They can be changed using the system's Setup utility.
DIMM Dual Inline Memory Module.
DMA Direct Memory Access. DMA allows data to be sent directly from a component (such as a
disk drive) directly to the memory on the motherboard. The processor does not take part in
the data transfer, which improves system performance.
EFI Extensible Firmware Interface.
EMI Electromagnetic Interference.
IFB I/O Firmware Bridge. A multifunction device on the I/O Board that acts as a PCI-based Fast
IDE controller.
LED Light Emitting Diode. The type of indicator used in this system.
LVDS Low-Voltage Differential SCSI.
OS Operating System.
PCI Peripheral Component Interconnect. PCI is the interconnect system between processors
and devices in the I/O expansion slots.
PIO Programmed Input/Output moves data between components in a computer so that all data
must pass through the processor.
POST Power On Self-test. The POST runs automatically during the server system startup
sequence.
RTC Real Time Clock. Keeps track of the time and date in CMOS memory. A battery backup
keeps the data intact when the server is off.
RFI Radio Frequency Interference.
SBE Single Bit Error.
SCSI Small Computer System Interface.
SDRAM Synchronous Dynamic Random Access Memory. SDRAM synchronizes with the bus
frequency.
VHDM Connectors used between the boards.
