									     Installing

And Upgrading Windows
           Functions of OS
• Must communicate, or provide a way to
  communicate, with the hardware
• Must create a user interface
• Must allow users to determine the
  available installed programs and run, use
  and shut down the programs of choice
• Must enable users to add, move and
  delete installed programs and data
                 Trait One
• OS is written for specific microprocessor (and
  support chipset)
• OS X, from Apple, won’t run on a PC
• OS must understand memory usage and limits,
  modes of operation and commands CPU
  understands
• OS and BIOS need to work together, or the OS
  goes around the BIOS
• OS needs method to add new hardware
  (drivers)
• OS should provide hardware error reporting
                Trait Two
• OS starts running when POST finishes
• Continues to run until PC is shut down
• Must “step out of the way” for applications
  to run
• Must provide “interface” or way to display
  available programs
• The shoe store
              Trait Three
• Applications need OS – can’t exist without
  it
• Applications expect the OS to provide
  resources
• OS hands off control of computer to
  application
• Should sense when application goes
  amuck and provide error message
               Trait Four
• OS must have flexibility to add new
  program(s) and hardware
• Should present applications and data in an
  orderly manner
• Should distinguish between applications
  and data
             Windows 9x
• 32-bit OS but designed with backward
  compatibility to Win 3.1 and DOS
• Tough job – and not without problems
• Dropped from A+ exams but there are still
  lots of systems running it
               The NT line
•   NT 3.1, 3.5 and 4.0
•   Windows 2000 in parallel to Win 9x
•   Windows 2000 server edition
•   Windows XP (2001) ended 9x family
•   Windows 2003 server
•   Windows Vista
                Mac OS
• Started with System 1, then 2 etc.
• Last build was System 9
• OS X is built on BSD UNIX with graphical
  user interface
• Windows continues to chase the Mac OS
  for graphics and ease of use
                  UNIX
• First written for trashed computer at Bell
  Labs
• Lots and lots of variants
• Lots of speed and power but at a big price
  in a hostile interface
• Linux is UNIX clone by Linus Torvalds
                  Preparation
•   Identify hardware requirements
•   Verify hardware and software compatibility
•   Clean install or upgrade
•   How to backup and restore data
•   Select installation method
•   Determine partition and file system
•   Computer’s network role
•   Computer’s language and locale settings
•   Plan for post-installation tasks
              Windows 9x
• Must partition and format hard drive before
  starting
• Don’t boot from CD
• Run SETUP to perform installation
• Text phase for initial drivers and file copy
• Restart
• Graphical phase and completion of setup
• Install all needed drivers
       Windows 2000 and XP
• Can start with blank disk (i.e. no partitions)
• Can boot from CD (some distributions of
  2000 require four boot disks)
• Text phase where you do partition and
  format work and file copy
• Reboot
• Graphical phase to finish installation
• Install all needed drivers
               Activation
• Registration is optional – will get you a
  flood of email from Microsoft
• Activation is required. Must be done within
  30 days of installation. I do it after all
  software is installed
• WE WILL NOT ACTIVATE XP IN THE
  LAB COMPUTERS!
         Installing 2000 and XP
• First setup screen offers F6 for disk driver; early SATA
  required driver disk (floppy only). A lot of drivers are
  copied to RAM
• Welcome screen is NOT where you start repair – that
  comes later. Press Enter here
• Must accept the EULA; F8 for this
• Next comes decision point. For blank disk, you can
  partition it (and undo previous partitions). If XP already
  there, you are asked if you want to repair existing
  (choose “R” option).
• Next is format (if partitions created)
• File copy for a bunch of files
          More on Partitions
• 2000 and XP can be installed on two
  partitions: System Partition (for boot files)
  and Boot Partition (for System files)
• Once it was thought wise to make System
  partition a FAT32 volume for easy boot
  from floppy disk. We got over that.
          Graphical Portion
• A lot more file copying and ad screens as
  Windows sets itself up
• Product key screen – have to have this
• (Please do NOT select a password for
  Administrator account)
• More file copy and configuration
• Install drivers for hardware
              Options - 1
• Scripting installations with Setup Manager
  is not for casual user
• You want this option when you have lots of
  systems to set up at one time
• Michael dances over the Product Key
  issue here
• Result is text file you hand to SETUP
              Options - 2
• Disk cloning – when all the hardware is the
  same, using Ghost
• Have to create new Security Identifier
  (SID) for each cloned system – not easy
• Fastest way to get multiple computers up
  and running
• Can also copy/install software
               Options - 3
• SysPrep. This is what HP, Dell, Gateway
  and others do for you
• Allows for different hardware in the
  systems
• User goes through short version of install
  to personalize the system
           Troubleshooting
• Often, just reboot and Windows will try to
  pick up where it left off
• SETUPLOG.TXT tracks the entire install
  process; in %systemroot%
• If you can, make sure hardware works
  before you start installation
• Hardware Compatibility List (HCL)
