Acpi 80860f14

On mainline kernels 5.10+, this ID should be automatically handled by dw_i2c via the baytrail_sem_platform quirk. If you still see errors, check your DSDT for custom modifications or consider updating your firmware.

This device is responsible for managing power states for the processor and other system components. If the driver is missing, your computer may not sleep or wake up correctly, or you may see a generic "Unknown Device" in your device list.

: Inserting a micro-SD or standard SD card yields zero response from the system. No new drive letter mounts, and Disk Management shows no changes.

: The Windows Device Manager presents a yellow exclamation icon, categorizing the hardware ID under "Other Devices". Acpi 80860f14

For developers and power users, the Linux kernel provides clarity. Running acpidump or ls /sys/bus/acpi/devices/ will show the device.

The 80860F14 controller acts as an interface between the CPU and Secure Digital (SD) or MultiMediaCard (MMC) storage. In many Bay Trail systems, this single controller handles multiple functions:

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. On mainline kernels 5

, 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

Hidden deep within the core configuration of countless laptops, tablets, and small form factor PCs is a vital, yet often overlooked, component identified by the string ACPI\80860F14 . This identifier might look cryptic, but it's the key to a critical piece of hardware found in millions of Intel-powered devices released since 2013. For developers, system administrators, and advanced users troubleshooting Linux or legacy Windows installations, understanding this specific ACPI ID is essential for getting a system's SD card slot and internal storage fully operational.

The DEV_0F14 interface is widely found across ultra-portable computers, 2-in-1 convertible tablets, and low-cost mini-PCs manufactured between 2014 and 2020. Notable devices relying on this driver include: If the driver is missing, your computer may

| Issue | Likely Cause | |-------|----------------| | I2C device (touchscreen, sensor) not detected | Driver not binding to 80860F14 | | i2c_dw probe failure | Missing _CID or invalid ACPI resources | | System hang after suspend | LPSS power domain not properly reset |

: Indicates the device is reported through the system’s motherboard BIOS/UEFI firmware layer rather than standard PCI bus plug-and-play enumeration.
