I think what's needed is some good documentation about CPU throttling, because people are intrigued when they see it, and wonder what it does and how you tune it. I know I was surprised when, for the first time ever, I was told I could throttle my Athlon XP - I didn't even know it could be. I know it's fairly experimental, but I think this feature needs better documentation and development - for example, at the moment it's possible to set the economy_mode value to 0, which shouldn't be allowed. Other than that, it's a fantastic ACPI implementation, I'd say it's the best of any OS! -- Bruce Cran To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
