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.

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.)
