For developers and tinkerers, the most reliable fix is to replace the broken ACPI table. Using tools like iasl (Intel ASL compiler) and acpidump, you can:
This is risky and beyond the scope of average users, but it is the only permanent solution for certain Chinese unbranded Bay Trail tablets.
If the installer fails or you prefer to do it manually:
Summary: This is a standard Intel hardware ID for power management. Installing the chipset drivers for your specific processor model (usually Bay Trail / Atom E3800 series) will resolve the error.
ACPI\80860F14 (often listed as ACPI\VEN_8086&DEV_0F14) identifies the Intel SD Host Controller, a hardware component primarily found in mobile and low-power devices powered by Intel "Bay Trail" or "Cherry Trail" processors. This controller manages communication between the system and its internal storage (eMMC) or external SD card slots. Device Identification & Function Hardware Name: Intel SD Host Controller.
Primary Role: It acts as the interface for eMMC flash memory and microSD/SD card readers.
Common Platforms: This identifier is frequently seen in 2-in-1 tablets, budget laptops, and mini PCs, such as the Microsoft Surface 3, ASUS E202SA, and Beelink BT3 Pro. Troubleshooting & Common Issues

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.
Would you like a downloadable PDF version, a concrete Linux kernel patch example for this HID, or a comparison with similar Intel ACPI IDs (e.g., 80860F41 for SPI)?
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.
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. For developers and tinkerers, the most reliable fix
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!
Understanding the ACPI\80860F14 Driver: A Guide to Intel SD Host Controllers
If you’ve ever ventured into the Windows Device Manager to troubleshoot a yellow exclamation mark or a "Missing Driver" error, you might have stumbled across a cryptic hardware ID: ACPI\80860F14.
While it looks like a string of random gibberish, this identifier is a crucial piece of the puzzle for mobile computing. Here is a deep dive into what this hardware ID actually is, why it matters, and how to get it working properly. What is ACPI\80860F14?
To decode this, we have to look at the two parts of the string:
ACPI: Stands for Advanced Configuration and Power Interface. This is an industry standard that allows the operating system to communicate with hardware for power management and configuration.
80860F14: This is the specific Plug-and-Play (PnP) ID. In the world of hardware, 8086 is the vendor ID for Intel, and 0F14 identifies the specific device.
Specifically, ACPI\80860F14 corresponds to the Intel BayTrail SD Host Controller. Where is this hardware found?
This hardware ID is almost exclusively found in tablets, 2-in-1 laptops, and ultra-low-power netbooks powered by Intel Atom Z3000 series processors (Bay Trail). Because these devices often use eMMC storage (an embedded MMC card) instead of a traditional SSD or Hard Drive, they require this specific controller to manage data flow between the processor and the storage/SD slot. Common Symptoms of a Missing Driver
If the driver for ACPI\80860F14 is missing or corrupted, you will likely notice one or more of the following issues: This is risky and beyond the scope of
Unknown Device in Device Manager: You’ll see "Unknown Device" under the "Other Devices" category.
SD Card Slot Not Working: You insert a MicroSD card, but the computer doesn't react.
Storage Performance Issues: Slow read/write speeds on the internal eMMC drive.
Power Management Issues: The device fails to wake up from sleep properly or the battery drains rapidly because the ACPI interface isn't managing the power states correctly. How to Install the ACPI\80860F14 Driver
Fixing this issue is usually straightforward, but the method depends on your device manufacturer. Since this is an Intel-specific component, you generally have three paths: 1. The Intel "SOC" Driver Package
Because this device is part of a "System on a Chip" (SoC) architecture, you rarely find a standalone driver for just the SD controller. Instead, you need the Intel Atom Processor Z3000 Series Driver Framework (often called the SoC Center or Intel Chipset Device Software). 2. Manufacturer-Specific Drivers
The most reliable way to fix this is to visit the support page for your specific device (e.g., Lenovo, ASUS, HP, or Dell). Search for your model number. Look for "Chipset" or "Platform" drivers.
Download the package labeled Intel Sideband Fabric Device or Intel BayTrail Chipset Drivers. 3. Windows Update
Sometimes, Windows Update fails to categorize this driver automatically. You can force a search by: Right-clicking the Unknown Device in Device Manager. Selecting Update Driver. Choosing Search automatically for drivers.
If that fails, click Search for updated drivers on Windows Update. Often, it will be tucked away in the "Optional Updates" section. Manual Identification Tip
If you are struggling to find the right file, you can verify the ID yourself: Open Device Manager.
Right-click the device with the error and select Properties. Go to the Details tab.
Select Hardware Ids from the dropdown menu. If you see ACPI\VEN_8086&DEV_0F14, you have confirmed you are looking for the Intel SD Host Controller.
The ACPI\80860F14 is the bridge that allows your Intel Atom-powered tablet to talk to its internal storage and SD card slots. If you're seeing this error after a fresh install of Windows 10 or 11, simply downloading the Intel SoC Driver package for your specific device model will typically clear up the error and restore your device's performance.
Are you currently seeing this as an "Unknown Device" in your Device Manager, or is the SD card slot itself not functioning?
