Explanation

The diskette is either not formatted or defective.
Replace it with a system diskette and press F1.

is not formatted. Insert a system diskette, press
F1, and format the hard disk as described in your
operating system manuals.

Make sure that the drive is correctly specified
with the BIOS Setup utility. If the problem

possible. Make sure that the Startup Devices
option is correctly specified with the BIOS Setup
utility. If the problem persists, consult your
