7 Power-On Self Test (Boot Check)
Outline of POST
The set has a boot check function called POST (Power-On Self Test) in it. The condition of the main body is diagnosed by checking
beep sound or error code.
z Start .............Test begins automatically when power switch is set to ON.
z Normal finish .....After memory checking, a beep sound is issued once and the set is placed into automatic stop.
Note: If no error occurs, nothing is displayed. (No display of OK, etc.)
Error Diagnosis by Checking Beep Signal Sound
The beep sound is as follows:
(1 (long sound) -2-3-4)
(Length of bar shows length of sound.)
= long sound (about 0.4 sec.),

8 List of Error Codes
<Only when the port replicator is connected>
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.
If your system displays one of except 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.
0200 Failure Fixed Disk
Fixed disk in not working or not configured properly. Check to see if fixed disk is attached
properly. Run Setup. Find out if the fixed-disk type is correctly identified.
0210 Stuck key
Stuck key on keyboard.
0211 Keyboard error
Keyboard not working.
0212 Keyboard Controller Failed
Keyboard controller failed test. May require replacing keyboard controller.
0213 Keyboard locked - Unlock key switch
Unlock the system to proceed.
0230 System RAM Failed at offset : nnnn
System RAM failed at offset nnnn of in the 64k block at which the error was detected.
0231 Shadow RAM Failed at offset : nnnn
Shadow RAM failed at offset nnnn of the 64k block at which the error was detected.
0232 Extended RAM Failed at offset : nnnn
Extended memory not working or not configured properly at offset nnnn.
0250 System battery is dead - Replace and run SETUP
The CMOS clock battery indicator shows the battery is dead. Replace the battery and run Setup
to reconfigure the system.
*0251 System CMOS checksum bad - Default configuration used
System CMOS has been corrupted or modified incorrectly, perhaps by an application program
that changes data stored in CMOS. The BIOS installed Default SETUP Values. If you do not
want these values, enter Setup and enter your own values. If the error persists, check the system
battery or contact Panasonic Technical Support.
0260 System timer error
The timer test failed. Requires repair of system board.
0270 Real time clock error
Real-time clock fails BIOS test. May require board repair.
*0280 Previous boot incomplete - Default configuration used
Previous POST did not complete successfully. POST loads default values and offers to run
Setup. If the failure was caused by incorrect values and they are not corrected, the next boot
will likely fail. On systems with control of wait states, improper Setup settings can also terminate POST and cause this error on the next boot. Run Setup and verify that the wait-state
configuration is correct. This error is cleared the next time the system is booted.
0281 Memory Size found by POST differed from EISA CMOS
Memory size found by POST differed from EISA CMOS.
13
02D0 System cache error - Cache disabled
Contact Panasonic Technical Support.
02F0: CPU ID:
CPU socket number for Multi-Processor error.
02F4: EISA CMOS not writable
ServerBIOS2 test error: Cannot write to EISA CMOS.
02F5: DMA Test Failed
ServerBIOS2 test error: Cannot write to extended DMA (Direct Memory Access) registers.
02F6: Software NMI Failed
ServerBIOS2 test error: Cannot generate software NMI (Non-Maskable Interrupt).
02F7: Fail - Safe Timer NMI Failed
ServerBIOS2 test error: Fail-Safe Timer takes too long.
device address Conflict
Address conflict for specified device.
Allocation Error for: device
Run ISA or EISA Configuration Utility to resolve resource conflict for the specified device.
Failing Bits : nnnn
The hex number nnnn is a map of the bits at the RAM address which failed the memory test.
Each 1 (one) in the map indicates a failed bit. See error 230,231 or 232 for offset address of the
failure in System, Extended or Shadow memory.
Invalid System Configuration Data
Problem with NVRAM (CMOS) data.
I/O device IRQ conflict
I/O device IRQ conflict error.
Operating System not found
Operating system cannot be located on either drive A: or drive C:. Enter Setup and see if fixed
disk and drive A: are properly identified.
Parity Check 1 nnnn
Parity error found in the system bus. BIOS attempts to locate the address and display it on the
screen. If it cannot locate the address, it displays ????. Parity is a method for checking errors
in binary data. A parity error indicates that some data has been corrupted.
Parity Check 2 nnnn
Parity error found in the I/O bus. BIOS attempts to locate the address and display it on the
screen. If it cannot locate the address, it displays ????.
Press <F1> to resume, <F2> to Setup
Displayed after any recoverable error message. Press <F1> to start the boot process or <F2> to
enter a Setup and change the settings. Write down and follow the information shown on the
screen.

Diagnostic Test Procedure
10.1. Equipment
(1) Test Computer ------------------------------------------------------------------------(2) IO BOX (CF-VEBU03) --------------------------------------------------------------(3) External Floppy Disk Drive (USB Port) -----------------------------------------(4) AC Adapter ----------------------------------------------------------------------------(5) External Printer -----------------------------------------------------------------------(6) Loopback Plug (Parallel Port Test) [P/N: DFWV95C0081] ----------------(7) Loopback Plug (Serial Port Test for RS232C) [P/N: DFWV95C0067] ---(8) Floppy Disk containing file DIAG ---------------------------------------------------
10.2. Preparation
(1) Connect the computer to the IO BOX (CF-VEBU03).
(2) Connect the AC Adapter and External Equipments.
(3) The System Setup should be set to the factory setting values by executing the "SETUP UTILITY"
which can be invoked by F2 key at the POST.
If not, the messages and items of the diagnostic test may not be displayed properly on the LCD.
(4) The serial port must be enabled in the "SETUP UTILITY" in order to execute the "1st SERIAL
PORT" test.
(5) Connect the serial loopback plug.
(6) In order to test the parallel port with Loopback Plug, disconnect the printer cable and connect the
parallel loopback plug with Power OFF.

Connect pins 3-4-7-9-10-12 to VC5 (PS/2 mouse plug pin 4) with 4.7KW each.
CAUTION
The plug described above must be used for servicing purpose only.
Do not use it for other than the above purpose and ensure that it remains confidential.
Using the plug enables the user to skip the previous password and disable the password.
1) Connect the parallel plug to the parallel port.
2) Connect the PS/2 mouse plug to the mouse port.
3) Power on the computer.
