I just don't know if this is a matter of oberman> code or a BIOS issue with no way out. Yup, I understand your needs. But, it is rather by design of acpi_thermal. However, you can stop passive cooling by setting hw.acpi.thermal.tz0.passive_cooling to zero even when passive cooling is active. You can do the following step: 1) sysctl hw.acpi.thermal.tz0.passive_cooling=0 2) Set your favorite CPU speed by dev.cpu.0.freq 3) sysctl hw.acpi.thermal.tz0.passive_cooling=1 Sincerely, -- Hajimu UMEMOTO @ Internet Mutual Aid Society Yokohama, Japan ume@mahoroba.org ume@{,jp.}FreeBSD.org http://www.imasy.org/~ume/
