Try a Took me a little bit to figure it out, but the module is built and loading. But, it doesn't provide anything useful. In fact, it doesn't provide anything at all. :( A kernel with CPU_ENABLE_TCC provides me with the hw.p4tcc sysctls that I can use to change the CPU frequency. A kernel without CPU_ENABLE_TCC doesn't give me any throttling / frequency settings. Loading the cpufreq.ko module doesn't change anything. This is on a Toshiba Satellite A60, bios 1.80c. It's a 2.8 GHz Celeron (P4). It's not the greatest BIOS or ACPI implementation. :( -- Freddie Cash, CCNT CCLP Helpdesk / Network Support Tech.
