Setting Up and Troubleshooting Hardware Components and Device Drivers

restarting your computer. Windows XP automatically identifies (enumer-
ates) the new hardware and installs the necessary drivers. Windows XP fully
supports computers with BIOS versions that are compliant with the
Advanced Configuration and Power Interface (ACPI) specification.
Windows XP also supports computers with certain BIOS versions that are
compliant with the older Advanced Power Management (APM) specifica-
tion.
Installing, Configuring, and Managing
Hardware
You might need to configure devices on Windows XP machines using the
Add Hardware Wizard in the Control Panel or by clicking the Add
Hardware Wizard button from the Hardware tab on the System Properties
window. Keep in mind that in most cases, you need to be logged on to the
local computer as a member of the Administrators group to add, configure,
and remove devices. Many devices completely configure themselves without
any administrator intervention at all; other devices require some administra-
tive effort.
Installing PnP Devices and Non-PnP Devices
Connect the device to the appropriate port or slot on your computer accord-
ing to the device manufacturer’s instructions. If the new device is not imme-
diately discovered by the operating system, you might need to start or restart
your computer. Plan for necessary downtime on production computers. PnP
is an enormous convenience, but it is not a replacement for preparedness. If
you are prompted to restart your computer, do so when it is appropriate. For
PnP devices, Windows XP should detect the device and then immediately
start the Found New Hardware Wizard. If a new device does not immedi-
ately install, you might need to use a special setup driver disk, CD-ROM, or
DVD from the manufacturer that ships with the device. If you are still unable
to install the device, or if you are installing a non-PnP device, perform the
following manual installation steps:
1. Click the Add Hardware icon in the Control Panel.
2. Click Next and then click Yes, I Have Already Connected the
Hardware. Click Next again.
3. Scroll down the Installed Hardware list to the bottom, select Add a
New Hardware Device, and click Next.
