anybody got some reliable, tested, known-good code for getting back to
real mode? I'm to the point where I have a working GDT, and paging is
turned off, but the last step -- turning off protection enable -- is not
working for me.
You want to be more explicit about why you want to get back?

well, I'll go check that. I'm finding that there is fair amounts of code
out there that is broken. Thanks to the wonderful PC bios you have a hard
time sometimes telling the difference between code that crashes into the
bios and code that actually works right, since the result is the same
either
