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:
To understand the problem, one must first understand the anatomy of the ID.
Put together, ACPI 80860F14 points directly to an Intel internal peripheral. According to Intel’s documentation and Linux kernel mailing lists, 80860F14 corresponds to the Intel SST (Smart Sound Technology) Audio DSP – specifically the Low Power Engine (LPE) audio controller found on Bay Trail-T and Bay Trail-CR platforms.
As of 2025-2026, Intel has largely moved away from the Bay Trail and Cherry Trail architectures. Newer platforms like Jasper Lake, Alder Lake-N, and later systems use different ACPI IDs or native PCIe enumeration for embedded controllers.
However, millions of devices with 80860F14 are still in active use—industrial panels, point-of-sale systems, older tablets, and embedded appliances. Understanding this ACPI ID remains relevant for maintenance, legacy support, and device recovery.
If the driver package does not automatically install:
80860F14 represents a recurring challenge in ACPI-based platform support: a vendor-specific HID without standard cross-OS driver binding. For Linux, reliance on compatible IDs (PNP0D10) and LPSS custom handlers is essential. Future x86 low-power SoCs increasingly move to _DSD + device tree overlays, reducing the need for such opaque IDs.

ACPI\80860F14 is a hardware ID for the Intel SD Host Controller
, a critical bridge component found primarily in mobile computing devices like tablets, netbooks, and affordable 2-in-1 laptops. This identifier is essential for the operating system to recognize and manage the hardware responsible for interfacing with and, in many cases, integrated flash storage such as eMMC drives The Role of the Intel SD Host Controller Acpi 80860f14
The primary function of the device represented by this ID is to facilitate communication between the system's processor and flash-based storage media. On devices like the Lenovo Miix 2 10 Acer Aspire ES1-131
, this controller is what allows the OS to read, write, and manage files stored on internal or external memory cards. Without the correct driver for ACPI\80860F14 , users often encounter two major issues: Invisible Storage:
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:
It often appears as an "Unknown Device" or "SD Storage Class Controller" with a yellow warning triangle in Windows Device Manager. Technical Context: Bay Trail and ACPI The identifier is closely linked to the Intel Bay Trail
platform (Atoms, Celerons, and Pentiums from the 2013-2015 era). The "ACPI" prefix indicates that the device is being enumerated via the Advanced Configuration and Power Interface
, a power management standard that tells the operating system about the hardware's capabilities and power states.
In some configurations, particularly when switching between "Legacy" and "UEFI" BIOS modes, this specific hardware ID may disappear in favor of a PCI-based ID like
, which can complicate driver installation for enthusiasts attempting to install older operating systems like on newer hardware. Finding and Installing Drivers For most users, this driver is included in the Intel Chipset Device Software Intel Serial IO Driver package provided by the laptop manufacturer. acpi\80860f14 free download - SourceForge
A very specific and technical topic!
The ACPI (Advanced Configuration and Power Interface) namespace is a complex and vast area, and without more context, it's challenging to provide a precise answer. However, I'll try to offer some general information related to the _SB namespace and the 80860F14 reference. If you see this ID listed under "Other
ACPI Namespace
The ACPI namespace is a hierarchical structure used to describe the hardware components of a computer system. The namespace is composed of a tree-like structure, with the root node being the _SB (System Bus) namespace.
_SB Namespace
The _SB namespace represents the system bus and is the top-level namespace for the system's hardware components. It contains child nodes that describe various system components, such as processors, memory, and I/O devices.
80860F14
The 80860F14 appears to be a hexadecimal value that might represent a specific register or identifier within the ACPI namespace. Without more context, it's difficult to determine the exact meaning of this value.
However, I found a reference to 80860F14 in the Intel ACPI Specification, which might be related to a specific register or field in the ACPI namespace.
Possible connection to Intel platforms
The 80860F14 value might be related to Intel platforms, specifically those using the Intel 8086 or 80860 processor families. The ACPI implementation on these platforms might use this value to configure or access specific hardware components.
Example ASL code
Here's a simple example of an ACPI Source Language (ASL) code snippet that uses the _SB namespace:
DefinitionBlock ("DSDT.aml", "DSDT", 2, "INTEL", "80860F14", 0)
_SB
// child nodes and definitions...
This code defines a DSDT (Differentiated System Description Table) with the _SB namespace as a child node.
Keep in mind that this information is speculative, and without more context or details about your specific use case, it's challenging to provide a more precise answer.
If you could provide more information about what you're trying to accomplish or what issue you're facing, I'd be happy to try and help you further!
The ACPI ID 80860F14 refers to the Intel Bay Trail SDHCI (Secure Digital Host Controller Interface). It is a critical component for devices like the Microsoft Surface 3 Go to product viewer dialog for this item. , Asus EeeBook X205TA Go to product viewer dialog for this item. , and various Intel Atom-based "mini PCs" and tablets. The "Ghost" Storage Controller
The most interesting feature of the 80860F14 is its "dual identity" in system firmware, which often leads to a tech-support mystery for Linux users:
ACPI vs. PCI Modes: In many Bay Trail systems, this hardware can be exposed to the operating system in two different ways depending on the BIOS/UEFI settings. In ACPI mode, it appears as ACPI\80860F14, but if the system is switched to Legacy/PCI mode, this ID disappears entirely and is replaced by PCI\VEN_8086&DEV_0F50.
The "Read-Only" Trap: Because this controller handles the internal eMMC (the main "hard drive" for many budget tablets), a mismatch in how the OS handles this ACPI ID can cause the internal storage to become permanently read-only or invisible during Linux installations.
A "High-Stability" Ritual: 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).

In Windows Device Manager, you may see an entry under “Other devices” labeled “Unknown device” with the Hardware ID ACPI 80860F14. No driver is loaded, and consequently, there is no audio.
While Bay Trail is now legacy (EOL 2020+), 80860F14 remains relevant in:
