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 in-
stalled. Others may indicate a problem with a device, such as the way it has been configured.
If your system displays one of the messages marked below with an asterisk (*), write down the
message and contact Panasonic Technical Support. If your system fails after you make changes
in the Setup menus, reset the computer, enter Setup and install Setup defaults or correct the
error. ( "List of Error Codes")
