Hm, not sure about this. There are a few places where the byte at offset 2 of the fsave frame if examined/modified, and that seems to be the same for both processors. Also, if i looked right, both linux and netbsd also only implement the FSP060 package in the kernel, that would mean those kernels would not work on 040.

 

But ill look again, maybe i missed something. If that is the case, then i need to integrate also the FPSP040 package in the program somehow.
