  • If the CPU wants data from RAM or the graphics card, it gets it via the Northbridge
    The Southbridge chip controls PCI and EIDE devices as well as ISA
    In the Athlon 64, the address bus is 64 bit
  • Burn-in failure is where a board dies due to a manufacturing defect – usually happens in first 30 days of use
    Can damage motherboard with static – always wear anti-static strap
    Intermittant faults= PC reboots itself, blue screen of death, example of Kate’s PC
    Determining that the motherboard is faulty is often after establishing that every other component is working properly
  • These are the main motherboard manufacturers

    1. 1. MOTHERBOARDS Jazz
    2. 2. INTRODUCTION TO MOTHERBOARD
    3. 3. WHAT IS MOTHERBOARD ?  Motherboard is called as a Headquarter of the system.  Motherboard is referred to as the Longest Printed Circuit Board of the System (PCB)  Motherboard is used to attach all the components and pass the instruction between the components to create the process inside the system.
    4. 4. IDENTIFICATION OF MOTHERBOARD  Motherboard is identified by its CPU socket number and available components  Some of the Identification are P-IV: PGA 478 P-III: PGA 370 P-II: SLOT 1 P-I: SOCKET 7
    5. 5. WHAT DOES MOTHERBOARD HAS MOTHERBOARD PORTS SLOTS CONNECTORS
    6. 6. MOTHERBOARD… MOTHERBOARD HAS 3 Major Division consisting of  PORTS  SLOTS  CONNECTORS
    7. 7. PORTS  PORTS is called as IN and OUT point of the system.  Basically the Ports on Motherboard are responsible for IN and OUT operations of the system.  There are various types of PORTS available at the Back Panel of the system
    8. 8. Types of Ports…..
    9. 9. SLOTS & CONNECTORS  SLOTS and CONNECTORS are available on board which is used to connect the Internal devices in the system.  SLOTS are used to connect various Cards while CONNECTORS are used to connect various Internal Devices  There are various type of SLOTS and CONNECTORS available On-Board
    10. 10. Types of SLOTS & CONNECTORS
    11. 11. OTHER OBJECT ON BOARD  NORTH BRIDGE  SOUTH BRIDGE  BIOS CHIP
    12. 12. OTHER OBJECT ON BOARD  NORTH BRIDGE: It is a chip which is closer to the CPU. It is responsible for handling the communication between the RAM and Processor  SOUTH BRIDGE: It is a chip which is closer to the I/O Slots. It is responsible for handling the communication between I/O port & RAM  BIOS CHIP: It maintains the System Setting
    13. 13. FULL DIAGRAM OF MOTHERBOARD
    14. 14. TYPES OF MOTHERBOARD MOTHERBOARD INTEGRATED MOTHERBOARD NON INTERGRATED MOTHERBOARD
    15. 15. INTEGRATED MOTHERBOARD
    16. 16. INTEGRATED MOTHERBOARD  Integrated Motherboard is a board which has everything In-built.  In these type of Motherboard all are on-board and does not require any kind of Cards  Some of the On-board things are DISPLAY,LAN,SOUND,MODEM,USB
    17. 17. NON-INTEGRATED MOTHERBOARD
    18. 18. NON-INTEGRATED MOTHERBOARD  Non-Integrated Motherboard is a board which has no Ports available.  These type of Motherboards require various kind of Cards to do input output operations  Some of the Cards available are are DISPLAY Card, LAN Card, SOUND Card, Internal MODEM,USB Card
    19. 19. How it all connects together backside bus L2 Cache Pentium CPU (in the CPU housing – on die) 32 bit address bus 64 bit data bus North Bridge RAM frontside bus L1 cache (Memory Controller) memory bus AGP AGP bus HDD scanner EIDE CD/DVD PCI South Bridge PCI bus sound ISA bus keyboard mouse FDD ISA modem BIOS
    20. 20. BUSES  BUSES are referred as the carrier of signals which are responsible for carrying the signals from one location to the other on the motherboard.  There are various type of BUSES available like ADDRESS BUS,DATA BUS,SYSTEM BUS
    21. 21. Troubleshooting Motherboards        Burn-in failure PC won’t boot Incorrectly seated RAM Incorrectly seated Graphics Card Power surges ESD Intermittant faults
    22. 22. Buying a motherboard     Intel or AMD processor Asus, Abit, Gigabyte, Tyan, Shuttle ATX case and ATX power supply Clock speed
