The following is a list of the messages that BIOS can display. Most of them occur during POST. Some of them display
information about a hardware device, e.g., the amount of memory installed. Others may indicate a problem with a device,
such as the way it has been configured. Following the list are explanations of the messages and remedies for reported
problems.
