This controller manages communication between your operating system and built-in flash storage, such as eMMC drives (common in budget laptops and tablets) or integrated SD card readers.
Intel no longer provides direct consumer downloads for Bay Trail drivers on their main website, but they distribute a comprehensive package through Microsoft Update Catalog.

In this comprehensive guide, we will dissect exactly what ACPI\80860F14 represents, why it appears as an error, which processors it affects, and—most importantly—how to resolve the driver issue permanently.
Some troubleshooting guides suggest disabling the "Unknown device" to remove the yellow mark. Disabling ACPI\80860F14 via Device Manager will: | Download and install the "Intel Bay Trail
Ensure the kernel is using the correct DMA mode; older kernels sometimes required the debug_quirks=0x40 flag to stabilize communication with this specific Intel controller. alpine-devel-2019-02.log
ACPI 80860F14 is a critical yet often overlooked component in Intel Bay Trail systems. While not a user-facing device, its correct operation is essential for basic input and sensor functions. The driver support is mature but can be problematic, especially on systems where the original OS was replaced (e.g., installing Windows 10 on an Android tablet or Linux on a Windows device). If not, install the chipset package
The ACPI identifier 80860F14 (often displayed as ACPI\80860F14 or INT33F4 ) represents a . This component is a core part of the chipset found in Intel's Atom, Celeron, and Pentium processors from the Bay Trail family (2013-2016).
While Windows Update often misses this specific driver, it is the easiest first step.
Before diving into the specific 80860F14 identifier, it is crucial to understand the ACPI standard. ACPI is an open standard that operating systems use to discover and configure hardware components. It acts as a middleman between the firmware (BIOS/UEFI) and the OS (Windows, Linux, etc.). When you see ACPI\VEN_8086&DEV_0F14 (the expanded version of the ID), it breaks down as follows:
