So far all I have found that is disabled that cpuinfo shows is mmx. I'm still looking tho. Also, I think the native setting is a setting that is known to be 100% safe. It is likely one of those things that if you use anything not safe and have problems, you get to keep the pieces. I think if the CPU supports it should be fine to turn but wanted to ask and make sure. I paid almost $200 for my CPU and I would like to get $200 out of it and use it all. I bought the whole thing so may as well use the whole thing. ;-) Thoughts? Dale :-) :-) -- I am only responsible for what I said ... Not for what you understood or how you interpreted my words!
