CPU-specific features...how to find them and/or enable them?
I have a dual AMD Athlon MP 1800+ system and would like to enable any and all cpu-specific features, such as 3DNow. I already have my computer running well as dual-cpu, but would like to enable as many other things as possible (as many programs i run, such as MPlayer, don't believe my cpu's use 3DNow).
How would I determine if these features are enabled/disabled and how would I go about enabling them? I thought adding them as USE-flags would do it, but I'm not sure if it actually worked.
Thanks in advance for any help :D
EDIT: i found what MPlayer thinks of my CPU's....here's what it found:
