Servicing the system may be required for replacement of some parts such as system board.

Go to numeric and text error codes

Remove any non-bootable floppy diskette that may be in the floppy disk drive. If the error message "OS/2!! SYS0145 OS/2!! SYS02027" is displayed a non-bootable floppy diskette is probably in the drive.
