Hello,
I played a bit with switching to pmode with both qemu and real
hardware, I've found one difference - real hardware (a Pentium machine)
does some checking of segment registers when switching to pmode
(enabling just PE bit); if contents is invalid, it probably raises some
exception (I have not had any interrupt handlers installed, so at me it
just probably triple-faulted). Qemu allowed me to continue even with
incorrect content of segment registers.
