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.
: It is commonly listed in Device Manager or system logs under several identifiers, including ACPI\VEN_8086&DEV_0F14 and its compatible ID Common Devices
ACPI 80860F14 is more than just an obscure string of characters; it is the key to enabling storage interfaces on a huge generation of Intel-powered budget devices. Its history is a microcosm of Linux driver development, showing how open-source engineers reverse-engineer and resolve firmware and hardware issues. Whether you’re a Linux user investigating a dmesg log or a Windows user hunting for a driver to get your SD card reader working, understanding that this ID points to the Intel Bay Trail/Cherry Trail SDHCI controller is the first step toward a solution. It serves as a powerful reminder that the software enabling our hardware is a living, evolving system built on layers of community and corporate effort.
The importance of correct support for the 80860F14 controller extends beyond the Linux ecosystem. Other major operating systems have incorporated drivers to handle this hardware. Acpi 80860f14
Hardware ID 80860F14 is specifically associated with the integrated into a family of Intel system-on-a-chip (SoC) processors. These SoCs were designed primarily for low-power, entry-level, and mobile computing devices. The primary families are:

, 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 As of 2025-2026, Intel has largely moved away
Here are some of the most common issues and their fixes:
grep . /sys/bus/acpi/devices/80860F14:*/status dmesg | grep -i "80860F14" cat /proc/interrupts | grep I2C
The secret to how 80860F14 can manage multiple functions lies in the _UID (Unique ID). This integer value, attached to the main ID, tells the kernel exactly which hardware block is being addressed. The Linux kernel uses a table to match _HID and _UID pairs to the correct driver slot. Its history is a microcosm of Linux driver
Ensure these options are enabled (not just modular):
The relevance of this driver is not just academic. As recently as 2025, users of on an Intel Compute Stick reported that their microSD slot was not detected. Analysis of the logs revealed that HaOS was detecting mmc0 and mmc1 , but no mmc2 device. In contrast, a standard Ubuntu system showed the correct device as mmc2: SDHCI controller on ACPI [80860F14:02] . This was ultimately traced back to the HaOS kernel missing a crucial patch for the 80860F14 controller, a stark reminder of how essential this driver is for full hardware functionality.
Some BIOS implementations "hide" the hardware under non-standard names. A known fix for devices like the involves dumping the ACPI tables and manually editing the DSDT (Differentiated System Description Table).
If you’ve ever tried to install Linux on an older Intel Atom "Bay Trail" device—like an Intel Compute Stick, a budget Acer Aspire, or a Microsoft Surface 3—you’ve likely hit a wall with the device ID.
. Without it, the system will not recognize inserted SD cards or its own internal eMMC storage. Linux Boot Issues
