Maybe for some applications. But it sounds to me as though this is talking about BIOS and hardware, not OS, and the BIOS and the hardware can't kill individual processes without OS cooperation - and if you have OS cooperation, then the whole thing is moot because the OS can do whatever it wants. But I too would much rather the hardware power itself down than fry. It would be still better for the OS to cooperate, but that requires that the OS have data reliable enough to base its decisions on. If the hardware has reliable sensors the OS doesn't, of course the best fix is to pass the accurate data to the OS, but that's often possible only with cooperation of the hardware maker. It's also possible the hardware has a binary "emergency over-temperature" sensor that's accurate enough to power down based on, and a less-accurate temperature sensor the OS can access. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
