I know it's the latest available from TYAN, but I'm not sure about my settings. Unfortunately, the BIOS itself is not well commented (right part of screen is often non-informative), and even more poorly documented (paper documentation is not synced with BIOS, and miss important features). Next time I boot, I'll take pictures of BIOS screens, so that I don't have to reboot every time I want to check something ;) One thing I know, is that loading cpufreq after boot time gave me an updated dev.cpu.0.freq_levels with about 20 values instead of 8. Powerd was able to lower cpu freq to the new lowest value, but was never able to increase it under load (and the reboot did not go very smoothly) thanks, Patrick
