Cause: This can happen when the Duplidisk ROM based setup utility is enabled. It can be bypassed two ways:
Corrective Action:

1. To boot from the diskette one time, remove the diskette from the drive and allow the auto boot utility to start. Then, select the "Continue booting system" option, insert the floppy disk into diskette drive and the system will start from the floppy normally.

2. Run the Duplidisk setup utility and disable the auto boot utility.
