The R8000 code was removed because it was unfinished work in progress. I wrote it without having access to hardware at the time. If somebody was submitted the code for inclusion in that shape I'd have to reject and consequently I removed the R8000 code again. I think we have sufficient knowledge about the R8000 to get it to work. And if necessary I know the folks who did the IRIX kernel work back in the dark ages. Ralf
