The code surely does not looks like that. The sysenter/sysexit bit, bit-11,
in cupid 1, edx.
Prokash (garlic.com), from the many questions you asked, the thing you are
doing looked like a project I did (but not finished because of layoff) with
my previous empolyer. It is most likely they are totally unrelated. Do you
mind if you could tell me in private for this particluar thing you are
working on, who are you working for?

The point of this question is to findout if the mode switching for XP is
still thru INT2E ( or Pentium II+ syscall/sysexit ) or thru combination of
both. XP hw requirement shows ( some 233 Mhz +, cant remember), and pentium
II stopped there. *Note that syscall/sysexit is relatively new
introduction…*

Considering XP supports the IA 64 I would have to say yes it does
support machines that don’t support that.
