Without the proper driver, this device will not function correctly, often leading to issues with SD card readers, internal eMMC storage, or general system stability. This article explains what the ACPI\80860F14 device is, why it fails, and how to fix it. What is ACPI\80860F14?
: On many Bay Trail devices, this controller manages the MicroSD slot. A faulty driver will disable the card reader.
Often, Windows Update can detect and install the appropriate driver automatically. Connect your computer to the internet. Go to . Click Check for updates .
This specific controller belongs mostly to Intel’s System-on-Chip (SoC) lineups, primarily the and Cherry Trail generations (such as Intel Atom, Celeron, and Pentium N-series processors). Because these platforms prioritize efficiency over raw desktop performance, they use eMMC storage chips soldered directly onto the motherboard rather than heavy SATA or NVMe solid-state drives. Acpi 80860f14
On mainline kernels 5.10+, this ID should be automatically handled by dw_i2c via the baytrail_sem_platform quirk. If you still see errors, check your DSDT for custom modifications or consider updating your firmware.
Identifier is the key to unlocking the storage potential of countless Intel Bay Trail and Cherry Trail devices. It works in conjunction with specific Unique IDs ( _UID ) to control various functions like eMMC storage, SD card readers, and SDIO-connected Wi-Fi. While it has a long history with Linux, its development and stabilization stand as a prime example of community-driven open-source collaboration.

: Indicates the device is reported through the system’s motherboard BIOS/UEFI firmware layer rather than standard PCI bus plug-and-play enumeration.
: Enthusiasts in the Porteus community have noted that to keep this controller stable, one must perform a specific "power cycle dance"—physically unplugging the power and waiting for a specific blue light sequence—before booting, otherwise, the BIOS may fail to "take inventory" of the SDHCI controller correctly. Key Specs & Role Primary Function Controls internal eMMC storage and external SD card slots. Common Platform Intel Atom Z3000 series (Bay Trail). Driver Support Managed by the sdhci-acpi driver in Linux. Wake Support
