Overview of the Diagnostic Tools
Diagnostic Error Messages
Diagnostic error messages appear when a test program finds a
problem with a hardware option. Normally, these messages are
text, but they can be numeric. The test programs will generate one
of the following return codes:
0 A return code of “0” indicates that the device
passed its test.
1 A return code of “1” indicates that the device
failed its test.
2 or higher A return code of “2” or higher indicates that the
test stopped.
Software-Generated Error Messages
These messages appear if a problem or conflict is found by an
application program, the operating system, or both. For an
explanation of these messages, refer to the information that comes
with your software package.
Troubleshooting Charts
The troubleshooting charts given in “Troubleshooting” on page 245
list symptoms of problems (for example, perhaps the symptom is
“the mouse is not working”), as well as steps to correct the
problems.
Option Diskettes
An optional device or adapter might come with a diskette. Option
Diskettes usually contain diagnostic files or configuration files that
the system needs to recognize and activate the option.
If your optional device or adapter comes with an Option Diskette,
you might need to install some configuration (.CFG) files or
diagnostic files (.EXE or .COM). See Chapter 4, “Installing Options”
on page 73 for instructions on installing the configuration or see
“Installing Additional Test Programs” on page 263 for installing
diagnostic files.
