CMOS checksum invalid, run SCU

CMOS RAM information has been corrupted and needs to be

 

reinitialized by running Computer Setup.

 

 

CMOS failure, run SCU

CMOS RAM has lost power and needs to be reinitialized by running

 

Computer Setup.

 

 

Floppy controller failed

The diskette drive controller failed to respond to the reset

 

command. Power - down the system and check all appropriate

 

connections. If the diskette drive controller continues to fail, you

 

may need to replace the system board.

 

 

Floppy disk track 0 failed

The diskette drive cannot read track 0 of the diskette in the drive.

 

Try another diskette. If the problem persists, you may need to

 

replace the diskette drive.

 

 

Floppy information invalid, run SCU

The drive parameters stored in CMOS RAM do not match the

 

diskette drives detected in the system. Run Computer Setup.

 

 

Hard disk controller error

The hard drive controller failed to respond to the reset command.

 

Check the drive parameters. Power down the system and check all

 

appropriate connections.
