Unformatted text preview: each device needs its own drivers. Sound cards often come with joystick ports, for example, ch08.indd 318 12/14/09 2:49:39 PM All-In-One / CompTIA Network+ All-in-One Exam Guide / Meyers & Jernigan / 170133-8 / Chapter 8 All-In-One Chapter 8: Expansion Bus 319 Figure 8-34 Installation menu and video cards often have built-in TV tuners. The Add Hardware Wizard will install all of the devices, but the installation CD brings them to your attention. Go for the CD program first and save the Add Hardware Wizard for problems, as you’ll see in the next section. NOTE To install drivers in a Windows computer, you need to have the proper permission. I’m not talking about asking somebody if you’re allowed to install the device.

(Not that I’ve ever had to use that feature, of course.) To access the rollback feature, simply open the Device Manager and access the properties for the device you want to adjust. On the Driver tab (Figure 8-35), you’ll find the Roll Back Driver button. ch08.indd 319 12/14/09 2:49:39 PM All-In-One / CompTIA Network+ All-in-One Exam Guide / Meyers & Jernigan / 170133-8 / Chapter 8 CompTIA A+Certification All-in-One Exam Guide 320 Figure 8-35 Driver rollback feature NOTE Many PC enthusiasts try to squeeze every bit of performance out o...
