Oops, that probably should be FORMAT (or FDISK for a multi-partition disk), not SYS. SYS puts the (MS-DOS) io.sys and msdos.sys files (and - version dependent - command.com file) on the already formatted disk/ partition. Anyway, as I said, the point is theoretical/moot, because other OSs can generate a boot sector, MBR, etc..
