If that shows something disabled that cat /proc/cpuinfo shows as
available, is it safe to turn it on? 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?
