Chapter 4: Managing Devices and Peripherals 5

MANUAL HARDWARE INSTALLATION

Legacy or non–Plug and Play hardware Requires you to manually configure the

communications settings. You can do this by using the Add Hardware Wizard or by running the installation disk provided

Manually configure the I/O (Input/Output)port, IRQ (Interrupt), and DMA (Direct Memory Access)

Use manufacturer’s installation disk

MANUALLY CONFIGURING RESOURCES

You can configure resources manually on certain devices to manage their settings. Be sure to emphasize that the settings you choose must match any BIOS, firmware, or jumper settings on the actual device to work

properly.

MANAGING AND TROUBLESHOOTING DEVICES

Windows XP usually manages devices automatically.

Update driver/rollback driver.

Verify resource settings on manually configured devices.

Hardware troubleshooters.

Chapter 4: Managing Devices and Peripherals 13

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.

Advanced Configuration and Power Interface - is a power management specification that allows the operating system to control the amount of power distributed to the computer's devices.

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.
