Why not? IIUC triple fault is exported as a cpu pin, which the
chipset/motherboard wires into the board-level reset line.

I think the bios can expect the IDE hardware (or any other device) to be
quiescent on entry. It doesn't make sense to initiate an explicit reset
immediately after boot; that would slow things down.
