Oh - reset on SMP. Good point. We'd need to find a reset mechanism
that worked even on SMP.
BTW, I tried the cf9, kbd controller, and triple fault reset on qemu.
Unfortunately, cf9 doesn't do anything, and the other two only soft
reset the cpu. A soft reset just causes POST to get called again in
an infinite loop.
Anyone know of a way to reliably hard reset qemu?

Boot loaders and OSes assume they can use the memory immiediately
above 1Meg - the BIOS isn't allowed to reserve it.
