Hi Johan, I have good news that I found out how the HPET is enabled and when it can be enabled. There may however be confusion as not all of the IXP chipsets actually even have the capability. It is only the SB450 versions A13 and above and the SB460 so the SB400 would be out of luck. We at AMD will look into getting the HPET turned on for the chips that have it. Thanks for the heads up -Joachim _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
