Managing Hardware Devices and Drivers

1
Managing Hardware Devices and Drivers

• Hardware includes any devices that were connected
  to your computer when it was manufactured, as
  well as peripheral equipment added later.
• Some devices are connected to expansion slots
  inside the computer.
• Some devices are connected to ports on the
  outside of the computer.
• Each device has its own unique device driver.

2
Hardware Types

• Microsoft Windows 2000 classifies devices by
  hardware type.
• Hardware types include individual devices.
• Devices can be classified according to how they
  connect to your computer.
• Devices can include several types of hardware.
• The Windows Hardware Compatibility List (HCL)
  lists Windows 2000supported devices.

3
Plug and Play

• Adheres to a set of specifications developed by
  the IEEE and computer and software manufacturers
• Allows a computer to automatically detect and
  configure a device and install the appropriate
  device drivers
• Works with the Windows 2000 Power Options utility
  to manage the power requirements of your hardware
  and peripherals

4
Installing Devices

• Connecting the device to your computer
• Loading the appropriate device drivers for the
  device
• Configuring device properties and settings

5
Uninstalling Devices

• You can usually uninstall Plug and Play devices
  by disconnecting them or removing them.
• You should notify Windows 2000 when uninstalling
  nonPlug and Play devices.
• You can disable a Plug and Play device rather
  than uninstall it.

Event Logs

• The System log can help you predict and identify
  the sources of system problems.
• The Application log and System log can help you
  confirm problems with software.
• Follow certain guidelines when you use event logs
  to diagnose problems.

12
Installing Service Packs

• Windows 2000 makes it easier for administrators
  to add service packs.
• Windows 2000 supports service pack slipstreaming.
• Windows 2000 eliminates the need to reinstall
  components applied before a service pack was
  installed.

13
Service Pack Slipstreaming

• Service pack slipstreaming refers to a service
  pack being applied to Windows 2000 distribution
  files.
• To apply a new service pack, use Update.exe with
  the /slip switch.
• Windows 2000 replaces several key files.

14
Post-Setup Installation of a Service Pack

• A service pack is applied on an existing Windows
  2000 system by running Update.exe.
• If the system state changes, Windows 2000
  installs the correct files, whether those files
  originate from the Windows 2000 installation
  CD-ROM or from the service pack.

15
Introduction to Windows Backup
16
Planning for Windows Backup

• Determine which files and folders to back up.
• Determine how often to back up.
• Determine which target media to use for storing
  backup data.
• Determine whether to perform network or local
  backup jobs.

Backup Types
19
Setting Backup Types for Specific Jobs
20
Combining Backup Types

• Normal and differential backups
• Normal and incremental backups
• Normal, differential, and copy backups

21
Performing Preliminary Tasks

• Before each backup job, ensure that the files to
  be backed up are closed.
• If you use a removable media device, make sure
  that several preliminary tasks are completed.

22
Selecting Files and Folders to Back Up
23
Specifying Backup Destination and Media Settings

• You must provide information for the backup media
  options.
• You must start the backup or specify advanced
  backup options.

24
Specifying Advanced Backup Settings

• When you specify advanced backup options, you are
  changing the default backup settings for the
  current backup job.
• You can configure a number of advanced options.
• You can choose to back up now or later.

25
Scheduling Backup Jobs

• A scheduled backup job occurs at a later time and
  is unattended.
• Windows Backup is integrated with the Task
  Scheduler service.
• Click the Later radio button on the When To Back
  Up screen of the Backup Wizard.
• The job is placed on the Windows Backup calendar.

26
Overview of UPS

• Disaster recovery is the restoration of a
  computer so that you can log on and access system
  resources after a disaster has occurred.
• An uninterruptible power supply (UPS) provides
  power if the local power fails.
• A UPS is usually rated to provide a specific
  amount of power for a specific period of time.

27
Configuring Options for UPS

• Use the UPS tab of the Power Options Properties
  dialog box to configure the UPS service.
• You must specify the COM port, the conditions
  that trigger the UPS device, and the time
  intervals for battery settings.

28
Testing a UPS Configuration

• You should test the UPS configuration to ensure
  that your computer is protected from power
  failures.
• You should not use a production computer to test
  the UPS configuration.
• You should wait until the UPS battery reaches a
  low level to verify that an orderly shutdown
  occurs.

29
Implementing Disk Fault Tolerance

• Fault tolerance is the ability of a computer or
  operating system to respond to a catastrophic
  event so that no data is lost or corrupted.
• Disk fault tolerance is not an alternative to a
  backup strategy.

30
Implementing RAID (Redundant Array of Independent
Disks)

• Software implementations
• Hardware implementations

31
Mirrored Volumes
32
RAID-5 Volumes
33
Mirrored Volumes vs. RAID-5 Volumes

• Mirrored volumes and RAID-5 volumes provide
  different levels of fault tolerance.
• Mirrored volumes offer read and write performance
  comparable to a single disk.
• Disk utilization improves with RAID 5.

34
Implementing RAID Systems
35
Safe Mode

• Safe Mode
• Safe Mode With Networking
• Safe Mode With Command Prompt
• Enable Boot Logging
• Enable VGA Mode
• Last Known Good Configuration
• Directory Service Restore Mode
• Debugging Mode

36
Recovery Console

• The Recovery Console is a text-mode command
  interpreter that is separate from the Windows
  2000 command prompt.
• The Recovery Console allows you to gain access to
  the hard disk of a Windows 2000 computer.
• You can obtain limited access to NTFS and FAT
  volumes.
• To start the Recovery Console, start the computer
  from the Windows 2000 installation CD-ROM or the
  Windows 2000 Setup floppy disks.

37
Emergency Repair Disk (ERD)

• Windows Backup includes a wizard to help you
  create the ERD.
• You should create an ERD when your computer is
  functioning properly.
• The Windows 2000 ERD does not contain a copy of
  the registry files.
• The backup registry files are in the
  systemroot\Repair folder.

38
Preparing to Restore Data

• Base your restore strategy on the backup type you
  used for the backup.
• Perform a trial restore periodically to verify
  that Windows Backup is backing up your files
  correctly.
• Keep documentation for each backup job.
• Keep a record of multiple backup jobs in a
  calendar format.

39
Selecting Backup Sets, Files, and Folders to
Restore

• The first step in restoring data is to select the
  data to restore.
• Use the Restore wizard to restore data.
• After you run the Restore wizard, you can finish
  the restore process or specify advanced restore
  options.

40
Specifying Advanced Restore Settings

• The advanced settings in the Restore wizard vary.
• After you have finished the Restore wizard,
  Windows Backup takes specific actions.
• You can configure a number of restore options.

41
Recovering from a Mirrored Volume Failure
42
Repairing a RAID-5 Volume

• Replace the failed drive, and then repair the
  RAID-5 volume.
• The fault tolerance driver reads the parity
  information stripes on the remaining members, and
  then re-creates the data contained on the missing
  member.
