Ok, we have a disconnect here. "standalone" mode is where doscmd
emulates DOS itself, "boot" mode is where you try to boot DOS.

That'd be a good start. The hardware emulation for the keyboard/mouse
controller is also a common stumbling block (later DOS versions' kbd.sys
hang trying to talk directly to the keyboard controller).
