Doing that would put the same operating system on the floppy as exists on the hard drive, but only if you booted to the hard drive. If the operating system on the floppy is already the same as the one on the hard drive there would be absolutely no point in doing this, although the operation would indeed work. A DOS system disk of any version will boot in any PC. Depending on the version number and the hard drive size and the BIOS limitations, drive C: might not be recognized by the system. If you boot to drive C: you can SYS A: with the DOS version that is running on C: Sam Heywood
