Presumably the machine is overheating or something that is causing the BIOS to request that the CPU speed is lowered (I wonder if Windows changes CPU speed when _PSS changes so that the BIOS writer figured changing _PSS was sufficient to force the CPU to be throttled). Presumably if the BIOS really is trying to protect the hardware not doing what it wants might result in physical damage to the machine of some sort. -- John Baldwin
