I'm currently writing Enhanced SpeedStep code for FreeBSD, and Intel's lack of documentation is getting in the way. I think I've managed to find the MSR with the data I need, but I need some people with Pentium M processors to run a quick test for me to verify this. In particular, I really need results from the new 90nm Pentium M processors (these are the ones with model numbers -- "Pentium M 735", "Pentium M 745", etc). What I need people with Pentium M processors to do is this: 1. Download and extract http://www.daemonology.net/tmp/dumpmsr.tgz 2. `make` 3. `kldload ./dumpmsr.ko` 4. `kldunload dumpmsr` When you kldload, it should print three lines; please send me those, along with the output of `sysctl hw.model`, and (if you know) the model name/number under which Intel advertises your processor. IF YOU ARE NOT RUNNING A PENTIUM M PROCESSOR, THIS WILL PROBABLY CRASH YOUR MACHINE. If I get the results I'm hoping for out of this, I'll probably have an Enhanced SpeedStep kernel module available for 5.x within the next week. Colin Percival
