Acpi 80860f14 -

The string ACPI\80860F14 follows a specific naming convention:

Therefore, 80860F14 is an Intel-specific ACPI identifier. But which component does it represent?

After extensive research, cross-referencing with Intel’s reference documentation, and analyzing Linux kernel source code (specifically the drivers/platform/x86 and drivers/i2c directories), we arrive at a clear conclusion:

ACPI 80860F14 corresponds to the Intel I2C (Inter-Integrated Circuit) Host Controller, often part of the Intel Bay Trail or Cherry Trail chipset families. Acpi 80860f14

If you see this ID listed under "Other Devices" with a yellow icon, it means Windows does not have the specific driver installed to recognize or communicate with the Intel Serial IO hardware.

This commonly happens after:

Windows does not natively include generic drivers for every embedded Intel I2C controller. The driver required is the Intel(R) I2C Host Controller driver, which is part of the Intel CHT (Cherry Trail) or BYT (Bay Trail) I2C Driver Set. Therefore, 80860F14 is an Intel-specific ACPI identifier

If you see ACPI\80860F14 flagged as an unknown device, it means:

The mainline kernel does not have a native driver matching 80860F14 directly. Instead, it relies on:

Workarounds: Many device trees or kernel patches add explicit acpi_device_id entries: Workarounds : Many device trees or kernel patches

static const struct acpi_device_id i2c_dw_acpi_ids[] = 
     "80860F14", 0 ,
     "PNP0D10", 0 ,
;

The 80860F14 controller manages the I2C bus #5 (or other designated bus) on the SoC. I2C is a two-wire, low-speed serial bus used to connect peripherals such as:

When the driver for this ACPI device is absent, users typically experience:

If the driver package does not automatically install:
