yep. And they still have to run dos 1.0, and that's why all the work is
done. A lot of the BIOS has to work behind DOS's back, which explains a
lot about why APM/ACMPI are so weird, not to mention all the weirdness in
the hardware that also dates back to 1980, such as shadow registers. Don't
get me started :-)
