PhoenixBIOS POST
Messages (Power
On Self Test)
Within POST, there are three kinds of messages:
Error messages: These messages appear when there is a failure in hardware, software, or firmware.
Informational messages: These messages provide information to the user but require no action.
Beep codes: This kind of warning sounds when POST errors occur and the screen is not available.
Because the OmniBook cannot be repaired by a service center below the FRU level, these messages will provided limited troubleshooting or repair information. However, the support specialist and service technician will be able to identify trends in repairs from these codes.
