This message remains on the screen for a few seconds.
If the self test is successful, the computer tries to load the operating
system.
Software The problems may be caused by your software or diskette. If
you cannot load a software package, the media (usually a
diskette) may be damaged or the program might be
corrupted. Try loading another copy of the software.
If an error message appears while you are using a software
package, check the software documentation. These
documents usually include a problem solving section or a
summary of error messages.
Next, check any error messages in the operating system
documentation.
Hardware If you cannot find a software problem, check your hardware.
First run through the items in the preliminary checklist above.
If you still cannot correct the problem, try to identify the
source. The next section provides checklists for individual
components and peripherals.
