Acpi\80860f14

If you are looking at a yellow exclamation mark in your Windows Device Manager next to an Unknown Device with the hardware ID ACPI\80860F14, you are dealing with a missing Intel SD Host Controller driver. This specific identifier is common on tablets, laptops, and 2-in-1 devices powered by Intel Atom, Celeron, or Pentium Bay Trail processors.

Here are a few options for a "good review," depending on where you are posting (e.g., a tech forum, a driver download site, or an IT support ticket).

Mostly fixed. The kernel now has a quirk table for 80860F14 that overrides broken ACPI data. However, you must ensure your kernel is compiled with CONFIG_I2C_DESIGNWARE_PLATFORM=y and CONFIG_I2C_DESIGNWARE_BAYTRAIL=y . Even today, some Ubuntu/Debian users need to add i2c_designware.acpi_quirk=1 to kernel command line. acpi\80860f14

A critical file for system stability on Intel-based mobile devices. Highly recommended if your hardware matches this ID."

Essential but Troubled. A workhorse of low-power x86 SOCs that has been a source of endless driver headaches, especially outside of its native Windows 8.1/10 ecosystem. Mostly fixed

This review is written from the perspective of a system administrator, Linux kernel developer, or advanced Windows power user dealing with low-level hardware enumeration.

Select Let me pick from a list of available drivers on my computer. Choose "System devices" or "SD host adapters."

A Lenovo Miix 320 (Bay Trail) running Ubuntu 22.04 – the touchscreen (Goodix) works perfectly after kernel 5.15. The same device running FreeBSD 13.1 – the I2C bus is detected but the Goodix driver never attaches.

This controller is responsible for managing internal storage (eMMC) or external SD card slots. It is a foundational component for mobile devices, as it allows the operating system to boot from and interact with flash-based storage. Why is the Driver Missing? The most common reasons for this error include:
