(OK, obviously, hehe.) What i don't understand and haven't solved is why it throttles so early (for me) to the point that int he middle of a compile (which is definitely NOT when you want it done ) when the load on the system, is definitely high enough to keep throttling from being needed. It's almost like (and anyone working on the ACPI code PLEASE do comment) whatever variable is responsible for the timing AND the differential for check times is screwy. That's all I have for now, meanwhile time for me to beat my head on why the hell BETA5 is screwing up on an installworld with touch: file not found for newvars.sh which exists in the directory it's trying TO copy from. -- David D.W.
