System Beep Codes
When an error that cannot be reported on the monitor occurs during a boot routine, the system may emit a series of beeps that identify the problem.
When a beep code is emitted, record it on a copy of the Diagnostics Checklist in " Getting Help ," and then look it up in Table 2 -6 . If you are unable to resolve
the problem by looking up the meaning of the beep code, use the system diagnostics to identify a more serious cause. If you are still unable to resolve the
problem, see "
Getting Help ."
