I have found some old posts on this click here and click here, but not much current talk.
what i assume would be needed is
- a puppy base
- a real-time Linux kernel source
- devx in the puppy and compile it.
Note: I have no experience building, or messing with a kernel. I might be totally wrong about the build process above.
If anybody in the, frendly and helpful, puppy linux community can help it would be appreciated.
