Is the Pentium D HPET capable?

[drule]

I'm beginning to wonder if my system (Pentium D based) even has HPET capabilities. It is nowhere to be seen in my BIOS, and the dump from my ACPI_HPET.bin (see below) seems to only contain "0" values.

There should be a HPET device in your DSDT at the address listed up there.

 

As far as I know it doesn't matter, AppleIntelCPUPowerManagement is the only thing that uses the HPET and you can't load that on a Pentium D system anyway.

 

If you need a HPET device present in ioreg for other purposes you can use netkas' HPETDevice.kext

Thanks for clarifying that. There is indeed one in my DSDT, which is why I wanted to know if it would be beneficial to remove it, as I thought the Pentium D couldn't use it.
