Regarding HPET issues on the X99 platform

[MizhiDR]

I use SSDT-Time to patch, but he prompts ：Locating HPET's _CRS Method/Name... - Could not locate _SB.PCI0.LPC0.HPET._CRS! Aborting! --> Appears to already be named XCRS! I tried the repair method you provided but still can't fix it. Do you have any other methods?

The SSDT-HPET supports different manual fixing methods: https://github.com/5T33Z0/OC-Little-Translated/tree/main/01_Adding_missing_Devices_and_enabling_Features/IRQ_and_Timer_Fix_(SSDT-HPET)#2-manual-patching-methods

If these don't work for you, you have to investigate furter.

You could try using OpCore Simplify in Windows. Maybe it can fix it for you.
