Somewhat more meaningful was "INT 19h" (CD 19), which also took 2 bytes and started the boot loader, bypassing the slow boot sequence of most systems.
And wouldn't a single instruction such as NOP or HLT be simply 1 byte?

I seem to remember the smallest MS-DOS program to be CD 20h saved as a `.com`.
