Chapter 5: Customizing Your Computer’s Hardware Devices
When you select Disk Drives in Device Manager, you’ll see a list of graphics cards
(display adapters) installed in the computer by manufacturer and model, such as
NVIDIA GeForce FX 5200. If the device supports Windows Display Driver Model
(WDDM), which is a requirement for Windows Vista Premium Ready computers,
this should also be listed (in most cases).
When you select Disk Drives in Device Manager, you’ll see a list of the DVD/CD-
ROM drives installed in the computer by manufacturer, type, and model. For DVD
drives, if you want to know the type of read/write disks your computer supports, this
is the place to check. The disk name should list DVD+RW if the DVD-ROM drive
can burn to DVD+R discs, DVD-RW if the DVD-ROM drive can burn to DVD-R
discs, or DVD+-RW if the DVD-ROM drive can burn to DVD+R and DVD-R discs.
Another tricky feature when burning DVD discs is the region code. Most DVDs are
encoded to play in specific regions. In the United States, your DVD player is most
likely set to work with Region 1-encoded discs. If you move to another country
because of deployment, transfer, or whatever, you may find that you need to change
the region code on your computer’s DVD-ROM drive. You can do this by right-
clicking the DVD-ROM drive in Device Manager, selecting Properties, and then
clicking the DVD Region tab, as shown in Figure 5-8. On the DVD Region tab,
select a country or geographic region and then click OK.
You can change your DVD-ROM drive only a limited number of
times—as per the “Changes remaining” value. When the “Changes
remaining” value reaches zero, you cannot change the region even if
you reinstall Windows or move the DVD drive to a different computer.
Human interface devices
When you select Disk Drives in Device Manager, you’ll see a list of the general-purpose
input devices that are configured specifically as human interface devices, including
mouse devices, trackballs, and keyboards. These devices are also listed under their spe-
cific device type.
IEEE 1394 bus host controllers
When you select Disk Drives in Device Manager, you’ll see a list of the IEEE 1394
host controllers installed in your computer. You won’t see this entry if your com-
puter doesn’t support IEEE 1394.
