Subject: [Qemu-devel] Checking of segment registers when switching to pmode
Date: Sun, 16 Apr 2006 15:29:31 -0000	[thread overview]
Message-ID: <1145201362.27237.11.camel@localhost> (raw)

  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.
