This is a "Mobile AMD Athlon(tm) XP-M (LV)2200+" (from /proc/cpuinfo) and has "PowerNow Technology" (from sticker on the machine). It has a variable-speed fan and under MS-XP (which it shipped with) the fan did change speed from time to time.
I have ACPI in the kernel, fan compiled in and "thermal zone" as a module. When it boots, the fan runs high for a few seconds, then down to some mid-speed and stays there. If I "modprobe thermal", then the fan goes off and stays off until the thing spontaneously powers off a few minutes later (from the heat, I gather). Also, acpi -V says "0 deg" after I modprobe thermal, which is probably why it decides to turn the fan off. I don't have anything in /proc/acpi/fan or /proc/acpi/thermal_zone... very odd. The box it's replacing has entries in both. J. David Zakar <[EMAIL PROTECTED]> wrote: > Which model of Athlon?
