That better work on all clones, since f000:fff0 is defined by the CPU,
not something else. If you've got an Intel 8088,8086,80286 etc. then
f000:fff0 is the address.

Also, a warm boot can be done by poking 0x1234 into location 0x472 prior
to jumping to f000:fff0, this will prevent the memory test but will
do everything else. This is what happens when Ctrl-Alt-Del is pressed.
