:> 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. : :-- :-Alfred Perlstein - [bright@wintelcom.net|alfred@freebsd.org] 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. -Matt Matthew Dillon <dillon@backplane.com> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
