mnfesq Posted April 26, 2011 Share Posted April 26, 2011 I am running 10.6.7 on a Dell Inspiron 1720 with the GM965 chipset / ICH8 mobo. It is fully functional and I am just fine-tuning it at this point. I noticed in IORegistry Explorer that I do not have HPET listed even though I am using the AppleHPET.kext and have a DSDT device for it. I compared my DSDT with others and found that the main difference is the following: Method (_STA, 0, NotSerialized) { If (LGreaterEqual (OSID (), 0x10)) { Return (0x0F) } Return (Zero) } I have tried to delete this code and when I do, I see HPET in IORegistry Explorer. However, I lose USB function. Obviously, USB function is more important than HPET but . . . Do I really have to choose between the two? Is there a way to figure out what the relationship is between this code and the code for my USB devices? Any assistance would be appreciated. I have attached my complete DSDT below. dsdt.aml.zip Link to comment https://www.insanelymac.com/forum/topic/255697-solved-hpet-and-usb/ Share on other sites More sharing options...
