POST Message Description
601 A failure occurred during testing of the diskette drive and
diskette-drive controller. This error can be caused by a loose or
incorrectly connected cable, a failing drive, or a failing system
board.
Note: The computer can be used, but one or more diskette drives
might not work.
Action: Verify that all diskette drive cables are properly installed
and securely connected.
Running the diagnostic programs might isolate the diskette drive
that failed, but you must have your computer serviced. (See
“Diagnostic Programs” on page 96 for information about
diagnostic programs provided with your computer.)
602 The computer is not able to start the diskette in the drive. The
diskette might be damaged or formatted incorrectly.
Action: Try another startable diskette that is formatted correctly
and is in good condition. (For information and instructions on
formatting diskettes, refer to “Formatting Diskettes” on page 43
and your operating system documentation.)
If this does not correct the problem, have the computer serviced.
604 A failure occurred during the testing of a diskette drive.

instructions on using the Configuration/Setup Utility program,
refer to “Configuring Your Computer” on page 22.)
2. Run the diagnostic programs. (See “Diagnostic Programs” on
page 96 for information about diagnostic programs provided
with your computer.)
3. If the diagnostic programs detect a failure, replace the diskette
drive.
If the problem cannot be isolated and corrected, have the computer
serviced.
