I forgot about them high-falutin fancy-dan C compilers that actually know what kind of ship they are running on.... and more importantly, take advantage of it. Now if software producers would start compiling their C code with compilers such as the Metaware High C compiler, maybe we could start using these advanced chips the way they were meant to be used. Of course that would leave out zillions of 8086/8088 machines, and that doesn't go well with the marketing department. I know that compatibility with older machines is important. I have heard all those lines. I guess that's why unix is running on my machine 80% of the time - no 640k memory barriers, no funny disk limitations, etc. A real operating system as opposed to a control program and device driver handler. :-) -- Steven C.
