When adding hardware to the inside of your computer, or to its serial or SCSI ports, the basic rules are:
Turn off the computer.
Plug in the hardware.
Turn on the computer.
For most modern hardware components, that's all there is to it. When you turn the computer on, a window announces that Windows 2000 has detected new hardware and is installing its software. You can use the new device immediately thereafter.
For external devices that plug into a USB port, FireWire port, or PC Card slot, the process is even simpler: Just connect the gadget. If it's a Plug-and-Play compatible device, Windows 2000 recognizes, configures, and installs the driver software for it automatically, without your having to turn off or restart the computer.
If your device isn't recognized when you plug it in, restart your computer.
The Add/Remove Hardware Wizard
Unfortunately, the Plug-and-Play system isn't foolproof. To install the drivers for older, non-Plug-and-Play hardware, or Plug-and-Play hardware that Windows 2000 doesn't recognize for some reason, run the Add/Remove Hardware Wizard like this:
Plug the new equipment into the computer, and turn the computer back on.
Choose Start → Settings → Control Panel. In the Control Panel window, double click Add/Remove Hardware.
The Add/Remove Hardware Wizard begins.
On the "Choose a Hardware Task" screen, the option you want ("Add/Troubleshoot a device") is already selected.
Click Next again.
Now Windows 2000 searches for new hardware. ...
