4 If that shows something disabled that cat /proc/cpuinfo shows as
5 available, is it safe to turn it on? So far all I have found that is
6 disabled that cpuinfo shows is mmx. I'm still looking tho.
8 Also, I think the native setting is a setting that is known to be 100%
9 safe. It is likely one of those things that if you use anything not
10 safe and have problems, you get to keep the pieces. I think if the CPU
11 supports it should be fine to turn but wanted to ask and make sure. I
12 paid almost $200 for my CPU and I would like to get $200 out of it and
13 use it all. I bought the whole thing so may as well use the whole
14 thing. ;-)
16 Thoughts?
