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 any of the below error messages other that the ones marked with an asterisk ( * ), write down the
message and contact your technical support office. 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.

.

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.

Keyboard not working.

Keyboard controller failed test. Requires repair of system board.

Unlock the system to proceed.

System RAM failed at offset nnnn of in the 64k block at which the error was detected.

Shadow RAM failed at offset nnnn of the 64k block at which the error was detected.

Extended memory not working or not configured properly at offset or address line nnnn.

The CMOS backup battery is dead. Replace the battery and run Setup to reconfigure the system

.

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 your technical support of fice.

The timer test failed. Requires repair of system board.

Real-time clock fails BIOS test. Requires repair of system board.

Real-time clock is illegal. Run Setup and set the date and clock.

Previous POST did not complete successfully . POST loads default values and of fers 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  t hat  t he  wait-state
configuration is correct. This error is cleared the next time the system is booted.

Contact your technical support of fice.

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 meory. 

.

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.

Displayed after any recoverable error message. Press <F1> to start the boot process or <F2> to enter a Setup and change the
