SYS.COM does not know about FAT32, although it can be used to prepare a bootable floppy disk. PC-DOS 7.10 will boot from a generic PC-DOS boot-sector.
Patched SYS.COM, without it sys commands, ie "a:sys:", will report "incorrect DOS version", with it sys commands will work correctly as PC-DOS 7.1 Rev 0 BLD134
