the system diagnostic programs are stored on a hidden partition on the computer hard disk. these programs are the primary method of testing the major components of your computer.

    you can also download the latest version of the diagnostics programs from http://www/ibm.com/pc/support/ and use the downloaded file to create an ibm enhanced diagnostics diskette. see “creating an ibm enhanced diagnostics diskette in windows” on page 14 for instructions.

    when using diagnostics with a usb keyboard and mouse attached, you must first enable usb emulation. complete the following steps to enable usb emulation:

    1. restart the computer and press f1 to start the configuration/setup utility.

    2. select devices and i/o ports.

    3. select usb setup.

    4. make sure that the usb keyboard and mouse are enabled.

    diagnostic error messages indicate that there is a problem; they are not intended to be used to identify a failing part. troubleshooting and servicing complex problems that are indicated by error messages must be performed by trained service personnel.

    sometimes the first error to occur causes additional errors. in this case, the computer displays more than one error message. always follow the suggested action instructions for the first error message that appears.
