    exercises you will be able to
  • Understand the overall process of operating
    system installation and upgrading
  • Prepare for operating system installation and
    understand the factors involved in making the
    decision to upgrade

3
Objectives (continued)
  • Install and upgrade the following operating
    systems and understand the various options
    presented in
  • Windows 2000 Server and Professional
  • Windows XP
  • Windows Server 2003
  • NetWare 6.0 and 6.5
  • Mac OS X

4
Objectives (continued)
  • Install Red Hat Enterprise Linux 3.0 and
    understand the basic differences between
    UNIX-type installation and those of other
    operating systems covered in this chapter
  • Review upgrading from one version to the next

5
Installing an Operating System
  • Varies from one OS to another
  • Certain features common to all installations
  • Installation involves
  • Checking the computer - meets or exceeds the
    hardware and/or software requirements for the OS
  • Ensuring that all equipment is powered on and
    operating correctly

6
Installing an Operating System (continued)
  • Floppy disks or CDs on hand
  • Understanding the general features of the OS
  • Up-to-date device drivers
  • Pertinent information available about your
    computer and peripheral devices

7
Installing an Operating System (continued)
  • May need to provide
  • Where to install the operating system
  • Type of installation
  • Information about you, your company, and your
    computer
  • Licensing information
  • Which components of the OS you want to install

8
Preparing for Installation
  • PC must be working correctly
  • Fix any defective hardware
  • Hardware turned on and ready for use
  • Information available about your hardware

9
Preparing for Installation (continued)
  • Obtain any special drivers
  • Many operating systems have minimum hardware
    requirements
  • Hardware compatibility list (HCL)
  • list that contains names and models for all
    hardware supported by the OS

10
Preparing for Installation (continued)
  • Enough time to complete OS installation

11
Upgrading an Operating System
  • General upgrade considerations
  • Backup and safety procedures
  • Specific steps to upgrade

12
Preparing for an Upgrade
  • Is upgrade necessary?
  • Information about system that may be needed
    during the upgrade
  • Make a complete backup of your current system and
    data before upgrading

13
Preparing for an Upgrade (continued)
  • Consider
  • whether you need to upgrade
  • whether the time is right to upgrade
  • Microsoft offers pre-releases in the form of
    alpha, beta, and release candidate (RC)

14
Preparing for an Upgrade (continued)
  • Production computer
  • computer used to perform real work
  • If unavailable would cause a loss of productivity
  • Check the computer against the requirements of
    the new OS

15
Preparing for an Upgrade (continued)
  • Keep records of custom software
  • Open Database Connectivity (ODBC)
  • rules on accessing databases
  • some databases may not be accessible when you
    upgrade

16
Making Backups Before Upgrades
  • Backup
  • copying files from a computer to another medium
  • important part of day-to-day computer operation
  • most operating systems have a backup utility

17
Making Backups Before Upgrades (continued)
  • Considerations when backing up your information
  • close everything before starting a backup
  • have the software needed to restore the backups
  • actually make a full backup
  • new system is able to read your backup without
    problems

18
Conducting a Test Upgrade
  • Test an upgrade before you do it to a production
    computer
  • Upgrade test is to simulate what would happen in
    a real upgrade
  • Discover any problems that might occur

19
Conducting a Test Upgrade (continued)
  • Deal with any software issues that arise
  • Test the computer for a couple of days
  • Repeat the test installation process starting
    with a clean computer
  • all unnecessary software and hardware have been
    removed
