Beep Codes

When errors occur during a boot routine that cannot be reported on the monitor, the computer may emit a beep code that
identifies the problem. The beep code is a pattern of sounds: for example, one beep followed by a second beep, then
followed by a burst of three beeps (code 1-1-3) means that the computer was unable to read the data in nonvolatile
random-access memory (NVRAM). If the system loses power and beeps constantly when you turn it back on, the BIOS is
probably corrupted.

video subsystem failure.
Storage device configuration in progress or storage
subsystem failure.
USB subsystem configuration activity in progress or
USB subsystem failure.
Memory subsystem configuration activity is in progress.

incompatible or in an invalid configuration.
Indicates routine system activity preceding video
initialization.
System resource configuration in progress.
Reserved for future use. This pattern is being
considered to indicate the Visual Off state on the
Dimension systems.
Indicates routine system activity subsequent to video
initialization.
Indicates End of POST process. Lights are normally in
this state briefly as POST completes. Once the hand-off
to the OS is done, the lights turn off and transition to
S0e state.
