14.3 Connecting New Gadgets

In books, magazines, and online chatter about Windows, you'll frequently hear people talk about installing a new component. In many cases, they aren't talking about physically hooking it up to the PCthey're talking about installing its driver software.

The truth is that you generally have to install both the hardware and the software. The ritual goes like this:

Run the installer on the setup disk, if one came with the new equipment.

Doing so copies the driver files to your hard drive, where Windows will be able to find it in the later steps of the installation.

Physically connect the gadget.

That is, connect it to the inside or outside of the computer, according to the instructions that accompanied the equipment.

The beauty of USB gadgets, FireWire gadgets, and PC cards is that they identify themselves to Windows XP the instant they're plugged in. For this kind of gizmo, there is no step 3.

Other kinds of gear aren't so lucky. In general, you must turn off your PC before connecting or disconnecting components from other kinds of connectors. When you turn it on again (after hooking up the new gadget), Windows XP examines every connector, port, and slot on your machine, checking to see whether or not it's now occupied by a piece of equipment it hasn't seen before.

Install the driver software into Windows.

If your new gear is Plug and Playcompatible (if its box bears a "Designed for Windows" logo, for example), then skip this step. The simple act of connecting the equipment inspires Windows to find the drivereither the one you copied to the drive in step 1, or one from its own database of drivers. (For nonPlug and Play gadgets, this step can require a considerable amount of effort, as described later in this chapter.)

NOTE

Windows XP comes with the driver software for thousands of different pieces of gear. It keeps many of these drivers, in compacted form, right there on your hard drive (in a file called Driver.cab). The Windows XP CD comes with hundreds of others.

All of these included drivers have been tested to work perfectly
with Windows XP. Furthermore, Microsoft adds to this collection as new
products appear, and sends you these new drivers via the Automatic
Update feature described in Section 9.23.6.

In either case, your gear is now completely installedboth its hardware and its softwareand ready to use.
