Reinstalling device drivers
When you reinstall device drivers, you are changing the cur rent configur ation of y our
computer. Reinstall device drivers only if you know that it is necessary to do so to
correct a problem with your computer. Copies of the device drivers that come
preinstalled on your IBM computer are located on the Recov ery and Diagno stics CD
in a folder called INSTALLS.
If you need to reinstall a device driver, refer to the INSTALLS folder on the CD and
choose the appropriate device subfolder. Rein stall t he de vice driv er usi ng one of the
following methods:
• In the device subfolder, look for a README.TXT file or other file with the.TXT
extension. Sometimes this file might be named after the operating system, su ch
as WIN98.TXT. The text file c onta ins information on how to reinstall that device
driver.

or

• Use the Add New Hardware program (located in the Windows Control P ane l) to
reinstall the device driver. Not all device drivers can be reinstalled in this
manner. If the device subfolder contains a file with an .INF extension, you can
use the Add New Hardware program. In the Add New Hardware prog ram, w hen
prompted for the device driver you want to ins tall, cli c k Have Disk and Browse.
Then select the appropriate device driver file from the Recovery and
Diagnostics CD.
or
• In the device subfolder, look for a SETUP.EXE file. Double-click the SETUP.EXE
file and follow the instructions on the screen.
