A segment of the main memory is allotted automatically depending on the computer’s operating status. The size of the Video

Memory cannot be set by the user.

Operation has been tested and conÞ rmed using Panasonic SD Memory Cards with a capacity of up to 2 GB.

The transfer rate using the SD Memory Card slot on this computer is 8

per second. (This is a theoretical value, and differs

MB

from actual speeds.)
The transfer rate is 8 MB per second even if you use an SD Memory Card that supports high-speed transfer rates.
Operation on other SD equipment is not guaranteed.
This computer is not compatible with MultiMediaCards or SDHC Memory Cards. Do not insert these kinds of cards.

*12

Theoretical value and not the actual speed. The transfer rate does not become higher even if you use a card that supports the

higher transfer rate.

The AC adaptor is compatible with power sources up to 240 V AC adaptor. The computer is supplied with a 125 V AC compat-

ible AC cord.

5 Power-On Self Test (Boot Check)

5-1

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

Start .............Test begins automatically when power switch is set to ON.

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:

6 List of Error Codes <Only when the port replicator is connected>

6-1

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 termi-
nate 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.

02D0 System cache error - Cache disabled

6-2

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.

Troubleshooting

7 Self Diagnosis Test

7-1

As for the self-diagnosis test(PC-Diagnostic utility) to use this model, a standard test and the
enhancing test by the module of the main body building in are possible.

Notes

1. Beginning of self-diagnosis test
1-1. Setting of content of setup

The power supply of the computer is turned on.

1.
" F2 " is pushed on the screen of "Panasonic" while " press <F2 to enter Setup> " is displayed.

2.
The setup utility starts and then takes notes of the content of the BIOS setup of present set.

3.
" F9 " is pushed, " Yes" is selected on the screen of " Is the default value loaded? ", and " Enter"

4.
is pushed.
" F10 " is pushed.

5.
" Yes" is selected on the screen of the setup confirmation, and " Enter" is pushed.

6.
The computer starts automatically.

7.

Attention

If the device which can be set is set to "Invalidity" by "Advanced" or "Security" menu, becomes an
error by "PC-Diagnostic utility".
(It is judged that the device which can be set to "Invalidity" by "Main" menu such as "Flat pad" is
normal if the controller operates normally though sets to "Invalidity" by the setup. )
In the model with built-in DVD of the USB connection, even if DVD is normal, becomes an error if
legacy USB is set to "Invalidity"

To skip BIOS password
Use <Ctrl>+<F10> key to skip BIOS password or authentication of fingerprint.
This key is only for entering DIAG mode. Not available to boot the computer.
If customer set "HDD Lock", the DIAG program cannot perform HDD test.
*This key is for service purpose only. Do not disclose this information to unrelated others.

1-2. When you execute an automatic test

1.

"Ctrl" + "F7" is pushed while the "Panasonic" start screen is displayed after the computer is started.

2.

The test of all devices begins automatically by "PC-Diagnostic utility"’s starting.

Attention

It is a test which the customer who bought PC can execute. (As for HDD, the enhancing test is also
possible.)
A flat pad does not work for a while after starting "PC-Diagnostic utility".
The movement of a flat pad might become abnormal If after RAM begins from the CPU/System
test, a flat pad will be operated in about 30 seconds. In that case,restarts pushing"Alt" + "Ctrl" +
