 failure 

or 

Fixed disk controller failure

A fixed (hard) disk drive is not working or not
configured properly. Check that the drive is
defined correctly in BIOS Setup. If necessary,
open the system unit and check that the drive’s
signal (ribbon) cable is connected.

Incorrect drive A type - run SETUP

The diskette drive is not correctly specified in
BIOS Setup.

Invalid NVRAM media type

Problem with NVRAM (non-volatile random-
access memory).

Keyboard error 

[

nn

] or 

Keyboard controller error

There is a problem with the keyboard or (less
likely) the standard I/O controller on the
motherboard. If POST discovers a stuck key it
displays its scan code.

Operating system not found

An operating system cannot be located either on
a system diskette or on a hard disk. Start BIOS
Setup and check that the diskette and/or hard
disk drives are specified correctly.

Parity check 1 

xxxx 

or 

Parity check 2 

xxxx

Parity error found on the system (1) or I/O (2)
bus. The BIOS attempts to locate and display
the address 

xxxx

. If it cannot locate the address,

it displays “????”.

Previous boot incomplete - default configuration
used

The previous POST did not complete
successfully. POST loads default values and
offers to start BIOS Setup. If the failure was
caused by incorrect values and they are not
corrected, the next boot will likely fail too.

Real-time clock error

Enter BIOS Setup and check your ‘Time’ and
‘Date’ settings.

System battery is dead - replace and run Setup

Replace the configuration battery as instructed in
the appropriate 

Motherboard Features & Upgrades

chapter, then use BIOS Setup to reconfigure the
system.
