  1. Chapter Overview • Understanding Automatic and Manual Hardware Installation • Configuring and Troubleshooting Hardware Devices • Viewing and Configuring Hardware Profiles • Configuring, Monitoring, and Troubleshooting Driver Signing • Configuring Computers with Multiple Processors

  2. Installing Hardware Automatically • Microsoft Windows XP Professional detects, installs, and configures most Plug and Play hardware automatically. • The appropriate driver must be available. • The basic input/output system (BIOS) must be Plug and Play or Advanced Configuration and Power Interface (ACPI). • Some non–Plug and Play hardware can be installed automatically.

  3. The Found New Hardware Wizard

  4. Using the Add Hardware Wizard • Start the Add Hardware Wizard to initiate installation of undetected hardware devices. • Windows XP Professional searches for new hardware devices. • Installs detected Plug and Play devices • Starts the Found New Hardware Wizard if it detects other new devices • Displays the Is The Hardware Connected page if it detects no new devices

  5. Confirming Hardware Installation

  6. Installing Hardware Manually • Determine which hardware resources are required. • Interrupts • Input/output (I/O) ports • Direct memory access (DMA) • Memory • Determine which hardware resources are available. • Use the Add Hardware Wizard to manually install the hardware.

  7. Changing Hardware Resource Assignments • Use Device Manager to instruct the operating system on device configuration. • Changing the resource assignments for a non–Plug and Play device does not change the resources used by that device. • To change the resources used by non–Plug and Play devices • Consult the device documentation • Determine whether switches or jumpers must be configured on the device

  8. Using Device Manager to Change Resource Settings • You must be logged on as a member of the Administrators group. • Policy settings on the network might prevent you from changing resource settings. • You can disable your hardware and cause your computer to stop working if you improperly change resource settings.

  9. Windows XP Professional Automatically Arbitrates Plug and Play Resources • Resource allocation among Plug and Play devices is not permanent. • If a Plug and Play device requests an already-allocated resource, Windows XP Professional can again arbitrate the resources to satisfy all devices. • Manually changing resources for a Plug and Play device prevents Windows XP Professional from arbitrating the assigned resources. • Plug and Play devices have a Resources tab in their Properties dialog box in Device Manager.

  10. Using Device Manager to Configure and Troubleshoot Devices

  11. Viewing Hidden Devices • At the command prompt, typeset devmgr_show_nonpresent_devices=1

  12. Installing and Configuring Fax Support • Windows XP Professional provides complete fax support. • You can send and receive faxes with a locally attached fax device. • You can send and receive faxes with a fax device connected on your network. • You can monitor and track faxes. • You must install and configure Fax Services.

  13. Managing and Troubleshooting Fax Support • Click the Outbox, right-click the fax in the details pane of the Fax Console, and then • To delete a fax, press Delete or click Delete on the File menu • To pause a fax, click Pause • To resume sending a paused fax, click Resume • To attempt to send a failed fax again, click Restart • To save a copy of a fax, click Save As • To mail a copy of a fax to someone, click Mail To • To print a copy of a fax, click Print

  14. Managing and Troubleshooting Fax Support (Cont.) • Click the Inbox, right-click the fax in the details pane of the Fax Console, and then • To delete a fax, press Delete or click Delete on the File menu • To pause a fax, click Pause • To resume sending a paused fax, click Resume • To save a copy of a fax, click Save As • To mail a copy of a fax to someone, click Mail To • To print a copy of a fax, click Print

  15. Fax Troubleshooting Scenarios • The fax does not print to a fax printer. • A fax you sent is pending in the Outbox. • The incoming fax device is not detecting a call. • You are using dialing rules with a calling card, but the calling card information is not working. • You cannot send faxes with Microsoft Outlook Express.

  16. Managing and Troubleshooting I/O Devices • Scanners, cameras, and other imaging devices • Mouse devices • Modems • Game controllers • Infrared Data Association (IrDA) and wireless devices • Keyboards

  17. Hardware Profiles • Store configuration settings for a set of devices and services • Are used primarily for portable computers • One hardware profile for the docked computer • Another hardware profile for the undocked computer

  18. Creating or Modifying Hardware Profiles

  19. Driver Signing • Microsoft digitally signs all Windows XP Professional drivers and operating system files. • In Device Manager, you can verify that the digital signer of the installed driver is correct.

  20. Configuring Driver Signing

  21. Monitoring and Troubleshooting Driver Signing • Use the System File Checker (SFC). • The SFC command and its options are:sfc [/scannow] [/scanonce] [/scanboot] [/revert] [/purgecache] [/cachesize=x]

  22. Using the Windows File Signature Verification Tool

  23. Scaling • Adding processors to your computer to improve performance • An issue for servers more than for computers running Windows XP Professional

  24. Updating Drivers

  25. Chapter Summary • For Most Plug and Play hardware, you connect the device to the computer and then Windows XP Professional automatically configures the new settings. • For the occasional Plug and Play or non–Plug and Play hardware device that Windows XP Professional does not identify, install, and configure, you must initiate hardware installation with the Add Hardware Wizard. • The Device Manager snap-in provides a list of all hardware resources and their availability, provides a graphical view of the hardware installed on your computer, and helps you manage and troubleshoot the resources.

  26. Chapter Summary (Cont.) • Use the appropriate hardware icon in Printers And Other Hardware on Control Panel to configure and troubleshoot a hardware device. • A hardware profile stores configuration settings for a set of devices and services. • The primary use of hardware profiles is for a portable computer that can use different hardware configurations depending on whether it is docked or undocked.

  27. Chapter Summary (Cont.) • Windows XP Professional provides two tools to verify the digital signatures of system files: SFC and File Signature Verification. • Adding processors to your system to improve system performance is called scaling. • If your computer only has a single processor, upgrading the driver is not going to make it a multiple-processor computer, and the upgrade could prevent your computer from running. • You use Device Manager to update drivers whenever a newer version of a driver is released or if you want to upgrade a driver.
