By demystifying this ACPI identifier, you have taken an important step toward mastering low-level hardware management on Intel-based embedded systems.
Hardware ID 80860F14 is specifically associated with the integrated into a family of Intel system-on-a-chip (SoC) processors. These SoCs were designed primarily for low-power, entry-level, and mobile computing devices. The primary families are:

Often, Windows can find this driver automatically, but it may require a "non-critical" or "optional" update. Open -> Update & Security -> Windows Update . Click Check for updates .
If Windows Update fails, you can download the driver manually from your device manufacturer (OEM) support page. Common systems using this ID include: : Models like the Steps for Manual Install: Download the Intel Serial IO Driver Intel SD Host Controller Driver for your specific laptop model. Extract the ZIP file. Device Manager , right-click the unknown device and choose Browse my computer for drivers Point it to the extracted folder and click 3.

If you encounter this device in an unknown state, do not panic. Install the Intel Serial IO driver, reboot, and watch the yellow exclamation mark vanish—replaced by a fully functional peripheral bus.
If the installer fails or you prefer to do it manually: The primary families are: Select
Understanding the syntax of an Advanced Configuration and Power Interface (ACPI) ID helps pin down the exact driver your system needs. Break down the identifier as follows:
The SD card slot may appear completely dead, or the system might fail to detect an internal eMMC drive, making the device unbootable or severely limited. Device Manager Errors:
In the kernel source code ( drivers/acpi/acpi_lpss.c ), Intel LPSS devices are defined with specific IDs. The 80860F14 entry enables the dw_i2c driver (DesignWare I2C).
