Provides connection ports such as for fans and switches. Provides a means for expanding and customizing the PC. Considered a field replacement unit (FRU) because it can be repaired on site. Importance to the PC Technician : Importance to the PC Technician Since the motherboard is the main hub of communication, it is vital that you are knowledgeable of motherboard architectures and communication systems. This knowledge will aid you in troubleshooting and upgrading PCs. Objectives : Objectives Identify major parts of a motherboard. Identify common motherboard form factors. Explain motherboard bus architecture. Identify expansion slot architectures. Identify the important system resources and explain what they are used for. Objectives : Objectives Identify and explain IRQs. Explain the role of a chipset. Explain the purpose of the CMOS Setup program. Explain the procedure for upgrading a Flash BIOS. Presentation Outline : Presentation Outline Motherboard Construction and Architecture Expansion Slots and Cards System Resources Troubleshooting Motherboards 1 2 3 4 Motherboard Construction and Architecture : Motherboard Construction and Architecture 1 Motherboard Backside : Motherboard Backside Motherboard Front Side : Motherboard Front Side Resistor Capacitor Socket Chip Expansion slot Bus Systems : Bus Systems Local bus (front side bus). I/O bus. Memory bus. Internal bus. Click each link for details. Local Bus : Local Bus The local bus connects directly to the CPU and provides communication to high-speed devices mounted closely to the CPU. I/O Bus : I/O Bus The I/O bus connects the CPU to the expansion slots. Memory Bus : Memory Bus The memory bus connects the CPU to memory. Internal Bus : Internal Bus The internal bus is inside the CPU. Other Busses : Other Busses Power bus sends power to all low-consumption devices such as speakers, lights, chips, CPU, and I/O cards. Data bus moves data between components. It is grouped as 8, 16, 32, and 64 bits. Control bus sends control signals from the CPU to system devices. Address bus connects the CPU to the main memory module. It identifies memory locations where data is to be stored or retrieved. Form Factors : Form Factors A form factor describes the physical shape or outline of a motherboard. Baby AT Full Size AT ATX LPX NLX Click each picture for details. BTX Baby AT : Baby AT Smaller than AT because of advancement in chip technology. 16-bit data bus. AT : AT Slightly larger than the XT. 16-bit data bus. Uses the DIN keyboard connector. Uses a serial port for the mouse. ATX : ATX Introduced in 1996. 16-bit data bus. Three common sizes. BTX : BTX Better system cooling and acoustics. Four common sizes. LPX : LPX Designed for low-profile desktop computer. Motherboard has no expansion card slots, just a slot for a bus riser card. Proprietary design. NLX : NLX Similar to LPX, except the bus riser card connects to side of the motherboard. Considered a standard; although, the length of the motherboard may vary. Backplane : Backplane A backplane is a circuit board with expansion slots. A CPU can be inserted into an expansion slot. Proprietary design. Two main classifications are active and passive. Original Motherboard Architecture : Original Motherboard Architecture Associated with the XT form factor. Single bus connects the CPU to RAM and to all components. The speed of the bus matches that of the CPU. XT : XT First standardized form factor. Developed in 1983 for the IBM PC. 8-bit data bus. Used the DIN keyboard connector. Serial port used for mouse. P8 and P9 connectors used for power supply connection. Later Motherboard Architectures : Later Motherboard Architectures CPU speed is different than the bus speed. Chipsets provide communication between different bus speeds. Chipset : Chipset A chipset is a collection of electronic circuitry required to carry out certain common motherboard functions. Divided into the north bridge and south bridge. BIOS : BIOS CMOS Setup Program and Data : CMOS Setup Program and Data CMOS Setup program is used to do the following: Identify system hardware. Set up power management. Enable/disable built-in devices and ports. CMOS data is stored in a volatile memory location in the chipset; needs a battery to keep from losing data. CMOS Setup Program : CMOS Setup Program CMOS Setup Program Access : CMOS Setup Program Access Review : Review Identify the expansion slots in the illustration. PCI 1. AGP 2. 1. Review : Review Identify the form factor of the motherboard in the illustration. ATX Review : Review Identify the form factor of the motherboard in the illustration. NLX (Courtesy of Intel Corp.) Review : Review Which of the following bus types is used to provide communication between high-speed devices mounted closely to the CPU? Data bus Internal bus Local bus I/O bus Review : Review Which of the following bus types is used to connect the CPU to the expansion slots? Data bus Internal bus Local bus I/O bus Review : Review The chipset is divided into the _____ bridge and _____ bridge. north, south (any order) Review : Review The _____ bridge of the chipset is used to control high-speed data systems. north Review : Review The _____ bridge of the chipset is used to control slower devices associated with the PCI and ISA buses. south You do not have the permission to view this presentation.
