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.
