After you have created a profile, you can control generally how Windows XP treats profiles by using the Hardware Profiles dialog box shown in Figure 6-20. (Open the System Properties dialog box, switch to the Hardware tab, and then click Hardware Profiles to access the dialog box.) First, you can specify how Windows uses hardware profiles during startup. You have the following options:

Have Windows wait until you select a hardware profile before it continues booting. Have Windows automatically select the first hardware profile on the list and con tinue booting after a specified amount of time. If you select this option, you can specify how long Windows should wait before going on without you. The default is 30 seconds.

Figure 6-20 Manage hardware profiles using the Hardware Profiles dialog box.
You can also specify the order in which hardware profiles appear on the list during startup. The order is important, mostly because it is the first profile on the list that Win dows will boot if you configure Windows to select a profile automatically. Select any profile on the list and use the up or down buttons on the right to move the profile around.
Configuring Hardware Settings for a Profile
After you have created the necessary profiles and configured Windows to display and start them the correct way, the next step is to configure hardware settings for each profile. To configure hardware for a profile, you must start the computer by using that profile. After you have started Windows by using a profile, use Device Manager to enable, disable, and configure individual devices. The settings you make will affect the cur rently loaded profile. The only tricky part of setting up hardware devices in profiles is actually remembering which profile you are currently using because neither Device Manager nor a device s Properties dialog box provides information on the current profile. You can always switch back to the System Properties dialog box and open the Hardware Profiles window to determine your current profile.
Selecting a Profile During Startup
After you create and configure hardware profiles, using them is easy. Whenever you start your computer, Windows displays a menu early in the boot process that looks like the one in Figure 6-21.

Figure 6-21 Choose a hardware profile during Windows startup.
By default, if you do not select a profile within 30 seconds, Windows loads the first profile on the list. If you configured Windows not to start a profile automatically, you will not see the timer at the bottom of the screen. Use the arrow keys to select a profile and press ENTER to start the computer.
Lesson Review
The following question is intended to reinforce key information presented in this les son. If you are unable to answer the question, review the lesson materials and try the question again. You can find answers to the question in the Questions and Answers section at the end of this chapter. 1.
You are helping a user who has recently configured a second hardware profile on her computer. She tells you that by following a friend s instructions, she copied an existing profile and then renamed it. She then restarted her computer so that she could configure her hardware for the new profile, but Windows did not display a menu that allowed her to select the new profile. What do you suspect is the problem

Lesson Summary
A hardware profile is a collection of configuration information about the hardware on your computer. Within a profile, you can enable or disable each piece of hardware (such as networking adapters, ports, monitors, and so on) or provide specific configuration information. To create a hardware profile, you must copy and then modify an existing profile. To configure hardware devices for use with profiles, you must start Windows by using a particular profile and then use Device Manager to enable, disable, and configure devices within that profile.
