Yes. The beta16 patch was indicated as being the candidate for RT Linux
2.0. I don't know if there is any difference between the two. I haven't
downloaded the 2.0 patch and tried it.

The smaller file is RT Linux: the patch, the module source code, and the
examples.

The larger file is the pristine Linux kernel source tree, already
patched for you. This saves you the trouble of going to www.kernel.org
to get the pristine sources and then patching it yourself. If you
download this, *don't* patch it again. Just skip the patch step and
proceed with making the RT Linux modules, examples, etc.
