MANAGING AND TROUBLESHOOTING DEVICES

Windows XP usually manages devices automatically.

Update driver/rollback driver. Verify resource settings on manually

configured devices. Hardware troubleshooters.

UPDATING DEVICE DRIVERS

Chapter 4: Managing Devices and Peripherals 14

DEVICE DRIVER ROLLBACK

Windows XP retains one previous version of each updated driver.

Roll Back Driver restores the previously installed driver version.

Roll Back Driver cannot restore drivers earlier than the previous version.

Chapter 4: Managing Devices and Peripherals 15

MANAGING DEVICE DRIVER SIGNING

Device drivers approved by WHQL are digitally signed.

Windows XP can be configured to not install unsigned drivers.

Chapter 4: Managing Devices and Peripherals 16

CONFIGURING MULTIPROCESSOR SUPPORT

Windows XP configures multiprocessor support automatically.

Do not attempt to manually configure the hardware abstraction layer (HAL).

Chapter 4: Managing Devices and Peripherals 17

MANAGING ACPI SUPPORT

Configured during installation. Press F5 to choose an alternative HAL; press

F7 to force a non-ACPI HAL. Do not change the HAL after installation.

SUMMARY

Windows XP can manage hardware automatically using ACPI and Plug and Play.

Hardware profiles allow multiple hardware configurations.

Windows XP can be configured to prevent installation of unsigned drivers.

Multiple CPU support is automatic in Windows XP.

HALs must be chosen during installation.
