RE: Does XP support machines that does not support th is

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.
