nnnn System RAM Passed

nnnn KB of system RAM has been successfully tested

CD-ROM drive Identified

The systems automatic drive type detection feature has identified the CD-ROM drive

Diskette drive A error; Diskette drive B Error

Drive A or B is present but has failed the BIOS POST

Ensure that the drive is installed correctly in the chassis and detected correctly in the system setup

Entering Setup

The system is starting the system setup program

Extended RAM Failed at offset: nnnn

Extended memory is not working correctly or is not configured correctly at offset: nnnn

IF you receive this message after making changes in the system setup program, enter the program and restore the original value(s)

Failing bits: nnnn

nnnn is a map of the bits at RAM address that failed the memory test.  Each 1 in the map indicates a failed bit

If you receive this message after making changes in the system setup program, enter the program and restore the original value(s)

Fixed Disk n Failure; Fixed Disk Controller Failure

The hard drive specified by n is not working or not configured correctly

Ensure that the drive is installed correctly in the chassis and defined coracle in the system setup program

Fixed Disk n Identified

The system’s automatic drive type detection feature has identified the hard disk drive(s)

Incorrect Drive x type – Run Setup

Diskette drive x is not correctly identified in the system setup program

Ensure that the drive is defined correctly in the system setup program

Invalid NVRAM media type

The system is having a problem accessing NVRAM (CMOS)

Set the configuration jumper to Maintenance mode and restart the system to return all settings to their defaults

Invalid system configuration data

The system configuration information is the system setup program is incorrect, or the battery charge may be low

Enter the system setup program and verify the system configuration, then restart the system

Keyboard controller error

The keyboard controller failed it’s test

If you receive this message after making changes in the system setup program, enter the program and restore the original value(s)

Keyboard error

The keyboard is not working correctly

The keyboard or system board may need to be replaced

Keyboard error nn

The BIOS has detected a stuck key represented by scan code nn

Make sure nothing is resting on the keyboard.  If a key appears to be stuck, carefully pry it up.  if the problem persists, you may need to replace the keyboard

Mouse initialized

The system’s mouse has been found and initialized

Operating system not found

The operating system cannot be located on drive A or drive C

Enter the system setup program and confirm that drive A or drive C is properly identified

Parity check 1 nnnn

A parity error has been detected on the system bus.  The BIOS attempts to locate the address and display it nnnn.  If it cannot locate the address, it displays ???? instead

If you receive this message after making changes in the setup program, enter the program and restore the original values(s)

Parity check 2 nnnn

A parity error has been detected on the I/O bus.  The BIOS attempts to locate the address and display it nnnn.  If it cannot locate the address, it displays ???? instead

If you receive this message after making changes in the setup program, enter the program and restore the original values(s)

Press <F1> to resume, <F2> to Setup

This message is displayed after a recoverable error message

Press <F1> to start the boot routine or <F2> to enter the system setup program and change any settings

Press <Del> to enter SETUP

Optional message displayed during POST

Id desired, press <Del> to enter the system setup program

Previous boot incomplete – Default configuration used

After a unsuccessful boot, POST loads default values

There may be incorrect values or incorrect settings in the system setup program.  Run the system setup program and attempt to restore the incorrect settings.  If the message reappears, set the configuration jumper to Maintenance mode and restart the system to return all settings to their defaults

Real time clock error

The RTC has failed the BIOS test

If you receive this message after making changes in the setup program, enter the program and restore the original values(s)

Resource allocation conflict on motherboard

The system cannot configure all system board devices without a resource conflict

Run the system setup program and try to resolve any obvious resource conflicts.  If the message reappears, set the configuration jumper to Maintenance mode and restart the system to return all settings to their defaults

Shadow RAM failed at offset: nnnn

Shadow RAM has failed at offset nnnn in the 64KB block in which the error was detected

If you receive this message after making changes in the setup program, enter the program and restore the original values(s)

System battery is dead – Replace and run SETUP

The CMOS clock battery indicator shows the battery is dead

Replace the battery and run the system setup program to reconfigure the system

System BIOS shadowed

The system BIOS has been copied to shadow RAM

System cache error – cache disabled

RAM cache failed the BIOS test.  The BIOS has disabled the cache

If you receive this message after making changes in the system setup program, enter the program and restore the original settings

System CMOS checksum bad – run SETUP

System CMOS has been corrupted or modified incorrectly, perhaps by an application program that changes data stored in CMOS

Run the system setup program and reconfigure the system by either reverting to the default values or by making your own selections

System RAM failed at offset: nnnn

System RAM failed at offset nnnn in the 64KB block in which the error was detected

If you receive this message after making changes in the setup program, enter the program and restore the original values(s)
