REPLACE AND PRESS ANY KEY WHEN READY

This is caused by an attempt to boot from a disk or diskette that is not
recognized as a system disk; that is no system files exist on the disk or
diskette.

floppy drive if a diskette is installed.
If you are trying to boot from the hard disk, make sure that you do not
have a diskette in drive A and press any key.
If you are trying to boot from floppy, insert a known good bootable
system diskette in drive A and press any key.
