I hope it does not. you can't preclude it, it may for compatibility sake (at the int 13h interface).

The latter, i.e. at the end of the first 512-byte block. Which means a PC BIOS can't boot normally from a medium such as a floppy with /smaller/ than 512 bytes sectors, but /bigger/ sectors are not a problem.
