Having just read Konstantin Boldyshev's introduction to FreeBSD assembly programming, I have a couple of questions. When I looked through some code in the source tree (and with a little background from the article), I noticed that INT 80 interface appears to be newer than an older interface, "CALL 7:0". When we was this change made and why? Why was INT 80 chosen? Since this is the same as Linux's 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.
