ACPI\80860F14 is a hardware ID for the Intel SD Host Controller
Are you trying to (like "Device not recognized") or
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: .
This driver allows your computer to communicate with the SD card reader, enabling you to insert SD cards for file storage. If this driver is missing, your SD card reader will likely not work.
When the motherboard's ACPI engine exposes ACPI\80860F14 but the operating system lacks the corresponding software stack, your computer will display several distinct failure modes: Acpi 80860f14
Here are some of the most common issues and their fixes:
: Indicates that the hardware interface is managed via the Advanced Configuration and Power Interface firmware layer.
In the Linux kernel, the sdhci-acpi driver provides support for SDHCI controllers enumerated via ACPI, using the PNP0D40 Compatibility ID. While the generic driver works broadly, Intel's specific implementation has required fine-tuning. As shown in the kernel source code, the sdhci_acpi_uids[] table uses the 80860F14 HID to assign different device descriptors based on the UID:
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
: 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
This tool can sometimes identify and update these controllers automatically.
Specifically, corresponds to the Intel BayTrail SD Host Controller . Where is this hardware found?
Before examining the device itself, it's important to understand the framework that identifies it. is the standard that allows an operating system to communicate with and manage the hardware components of a computer. ACPI tables are stored in a system's BIOS/UEFI firmware, providing the OS with a blueprint of the available devices, their power states, and their system resources. When the motherboard's ACPI engine exposes ACPI\80860F14 but
This hardware ID is almost exclusively found in tablets, 2-in-1 laptops, and ultra-low-power netbooks powered by (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
A typical DSDT entry includes:
Used for expandable storage via microSD or SD cards. Common Issues
