If a beep code is emitted, write down the series of beeps and then look it up in
. If you are unable to resolve the problem by looking up the meaning
of the beep code, use system diagnostics to identify the possible cause. If you are still unable to resolve the problem, see "

Table 2-
6. System Beep Codes
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).
