The 80860F14 entry tells the OS: "There is an SST Audio DSP here, and it is connected to a codec at I2C address 0x1A." However, the ACPI tables often fail to properly provide:

If the driver for ACPI\80860F14 is missing or corrupted, you will likely notice one or more of the following issues: Acpi 80860f14

The ACPI 80860F14 has been associated with various meanings and implications, including:

80860F14 is a used in ACPI (Advanced Configuration and Power Interface) tables, which your computer's firmware (BIOS/UEFI) provides to describe hardware to the operating system. This specific ID corresponds to an Intel SD/MMC/SDIO host controller , a part of the chipset responsible for managing storage interfaces like SD cards, eMMC flash storage, and SDIO devices (like Wi-Fi/Bluetooth combo cards). This fix enabled Wi-Fi and Bluetooth modules on

This table was significantly improved in 2016 when developer Daniel Drake added support for the UID 2 SDIO bus. This fix enabled Wi-Fi and Bluetooth modules on many Cherry Trail devices, such as the ECS EF20 laptop and Chuwi Hi10 tablet, which were otherwise non-functional.

When the driver for this ACPI device is absent, users typically experience: : Because this controller handles the internal eMMC

The ACPI Plug and Play Hardware ID 80860F14 corresponds to a proprietary Intel device found primarily on Bay Trail and Cherry Trail system-on-chips (SoCs). This paper examines the device's identification, its role in power management and I2C controller operation, and the challenges it presents for open-source operating systems.

: 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.

This device is a critical bridge between your computer's operating system and its flash storage.

Without the proper driver, this device will not function correctly, often leading to issues with SD card readers, internal eMMC storage, or general system stability. This article explains what the ACPI\80860F14 device is, why it fails, and how to fix it. What is ACPI\80860F14?
