:> interface, does this simplfy Linux emulation? Hinder it?
:>
:> Also, this is more general, what does "CALL 7:0" do?
:>
:> Sorry for the silly question, I got curious.

:I could be totally off base, but I'm pretty sure (from memory) that
:the lcall interface is the ICBS interface (some standard for x86
:unix binaries), the int 80 interface is supposedly quicker on more
:recent CPUs so it's now the default.
:
:I'm pretty certain that FreeBSD will still honor any program that
:uses the lcall interface.

Yes, your right. int 80 is considerably faster then lcall which is why
we moved to it. FreeBSD will definitely honor any program
using the old interface.
