30 About Your System
Warning Messages
A warning message alerts you to a possible problem and prompts you to respond before the system
continues a task. For example, before you format a diskette, a message will warn you that you may lose all
data on the diskette. Warning messages usually interrupt the task and require you to respond by typing
y
(yes) or
n (no).
NOTE: Warning messages are generated by either the application or the operating system. For more information,
see the documentation that accompanied the operating system or application.
Diagnostics Messages
When you run system diagnostics, an error message may result. Diagnostic error messages are not
covered in this section. Record the message on a copy of the Diagnostics Checklist in "Getting Help" on
page 129, and then follow the instructions in that section for obtaining technical assistance.
Alert Messages
Systems management software generates alert messages for your system. Alert messages include
information, status, warning, and failure messages for drive, temperature, fan, and power conditions. For
more information, see the systems management software documentation.
