Fixing NVRAM

This SSDT is required for all "true" 300 series motherboards and newer(Z370 is excluded), it specifically brings back NVRAM support and requires very little configuration for the end user.

  • B360
  • B365
  • H310
  • H370
  • Z390
  • 400 series (Cometlake)
  • 495 series (Icelake)

By default it uses PCI0.LPCB for the PCI and LowPinCount path. The device names can vary between PC00 and PCI0 for PCI path and LPCB, LBC and LBC0 for LowPinCount path. To see what you have:

  • Finding the LowPinCount path:
    • Intel: Search Name (_ADR, 0x001F0000)
  • Finding the PCI path:
    • Intel: Search PNP0A08 (If multiple show up, use the first one)

Now you're ready to compile the SSDT!
