I think the BIOS reboots from MSDOS, the same way as Linux does it.
I have several motherboards for which this doesn't work (maybe they are
all misconfigured). So, I have a patch, if you are interested, which
reboots in much the way you suggested. (I.e., switch to real mode and
jump to the BIOS reset routine).
