Title: Motherboard


1
COMP2060
  • The Motherboard

2
Types of Motherboards
3
Types of Motherboards
4
Main Components on a Motherboard
  • CPU and its chip set
  • System clock
  • ROM BIOS
  • CMOS configuration chip and its battery
  • RAM
  • RAM cache (optional)
  • System bus with expansion slots
  • Jumpers and DIP switches
  • Ports directly on the board
  • Power supply connections

Selection of a Motherboard Determines
se refiere a un grupo de circuitos integrados, o
chips, que están diseñados para trabajar juntos.
  • CPU types and speeds
  • Chip set on the board
  • Memory cache type and size
  • Types and number of expansion slots ISA, PCI,
    and AGP
  • Type of memory ECC, EDO, SDRAM, SIMMs, or DIMMs
  • Type of memory what kind of and how much SRAM
    and DRAM

Comment
  • El Chipset es el que hace posible que la placa
    base funcione como eje del sistema, dando soporte
    a varios componentes e interconectandolos de
    forma que se comuniquen entre ellos haciendo uso
    de diversos buses.

9
Selection of a Motherboard Determines
  • Type of case
  • ROM BIOS
  • Type of keyboard connector
  • Presence/absence of proprietary video and/or
    proprietary local bus slots
  • Presence/absence of IDE adapters and SCSI
    controller
  • Presence/absence of COM ports, LPT ports, and
    mouse port

10
Considerations When Selecting a System Board
  • Support the CPU you plan to use?
  • Type of BIOS?
  • Bus speeds and type of memory memory capacity?
  • Use many embedded devices?
  • Fit the case?
  • Warranty? How much manufacturer support?
  • How extensive and user-friendly is documentation?

11
Major Manufacturers o Motherboards
12
The System Clock
  • Keeps the beat for motherboard activities
  • Frequency is measured in megahertz (MHz)
  • Wait state
  • Occurs when the CPU must wait for another
    component

13
How the CPU Works
  • Input/output (I/O) unit
  • Manages data and instructions entering and
    leaving the CPU
  • Arithmetic logic units (ALUs)
  • Do all comparisons and calculations
  • Control unit
  • Manages all activities inside the CPU itself

21
CPU Slots and Sockets
  • The physical connection used to connect the CPU
    to the system board
  • Slots 1 and 2 are proprietary Intel slots
  • Slot A is a proprietary AMD slot
  • Current CPU sockets are called zero insertion
    force (ZIF) sockets and have a small lever on the
    side of the socket that lifts the CPU up and out
    of the socket

The Chip Set
  • Set of chips on the system board that
    collectively controls the memory cache, external
    buses, and some peripherals
  • Intel dominates the market
  • Most compatible with Pentium family of CPUs
  • Investment in RD has led to other developments
    (eg, PCI bus, universal serial bus, AGP, and
    Accelerated Hub Architecture)

29
Chipset
  • El chipset es el que se que conecta con el
    microprocesador con el motherboard, y por lo
    tanto, con el resto del equipo. Este se compone
    de dos partes básicas - el northbridge y el
    southbridge. Todos los diversos componentes de la
    computadora pueden comunicarse con el CPU a
    través del chipset.

Chip Set Manufacturers
33
According to "Guide to managing and maintaining
your PC" by Jean Andrews the three most common
BIOS are
  • 1. AMI BIOS 2. Award BIOS 3. Phoenix BIOS

Hardware Configuration
  • Tells CPU what hardware components are present in
    the system and how they are set up to interface
    with the CPU
  • Provided on motherboard in three ways
  • DIP switches
  • Jumpers
  • CMOS

36
Setup Data Stored by DIP Switches

How to Access CMOS Setup
41
Coin-Cell CMOS Battery
42
CMOS
  • Setting startup passwords in CMOS
  • Categories of CMOS settings
  • Standard CMOS setup
  • Advanced CMOS setup (aka BIOS Features setup)
  • Advanced Chip Set Setup
  • Power Menu (aka Power Management)
  • IDE HDD Auto-detect Hardware Device Settings (on
    jumperless motherboards only)
