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. The
beep code is a pattern of sounds; for example, one beep followed by a second beep and then a burst of three beeps (code 1-1-3) means that the system was
Non-system disk or disk error Faulty diskette, diskette drive subsystem,
or hard-disk drive subsystem Replace the diskette, CD-ROM, or hard-disk drive. If the
problem persists, replace the system board. See "
