is a specification used to outline motherboard configuration and dimensions in an effort to improve standardization.
ATX
Four or six wire power supply connector that connects to the motherboard.
Auxiliary Connector
Short for Basic Input/Output System, is a ROM chip located on all motherboards that allows you to access and set up your computer system at the most basic level.
BIOS
Some number of short beeps that are sounded by the BIOS upon startup when a memory, cache or processor error is encountered.
Beep Codes
Brains of the computer where most calculations take place.
CPU
Is an architecture that offers breakthrough performance for the motherboard through efficient memory utilization and Direct AGP.
DVMT
Is a connection or port located inside a computer on the motherboard or riser board that allows a computer hardware expansion card to be connected.
