Making foreign DOS boot floppies (IBM).

Up to now the way I've made bootable floppies of any necessary DOS version by shutting down my master system, rebooting to the appropriate floppy, format/s, copy, then reboot the master system to disk, which works but is pretty time consuming. What I'd like to do is all of this with the master running the normal higher-version O/S. I've gotten this far: Step one seems to be generic: format command. Step two is ? Step three is to copy IO.SYS, MSDOS.SYS Step four is to mark IO.SYS, MSDOS.SYS with attrib as System, Hidden, and Read-Only. Step five: copy COMMAND.COM,CONFIG.SYS,AUTOEXEC.BAT and then the rest of DOS. Apparently all DOS 3.5" floppies are FAT format with the capacity is 1,457,664 bytes, regardless the version, after accounting for the two hidden files, so... Is there a way I can patch or debug the floppy after generic format to make it look bootable? John A. or should I say Hi Fred?
