Find the device SDHB or SDHC and ensure the _HID (Hardware ID) is correctly set to "80860F14" .
If your laptop is "missing" its hard drive during a Windows setup, or your SD card isn't working, the driver is the likely culprit. Ensure you install the Intel Serial IO or Sideband Fabric Device drivers provided by your laptop's manufacturer to restore functionality.
Understanding the syntax of an Advanced Configuration and Power Interface (ACPI) ID helps pin down the exact driver your system needs. Break down the identifier as follows:
Chuwi hi10/hi12 (Cherry Trail tablet) soundcard not recognised Acpi 80860f14
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:
The hardware identifier (often seen as ACPI\VEN_8086&DEV_0F14 ) specifically identifies the Intel SD Host Controller found in Intel Atom, Celeron, and Pentium processors—most commonly from the "Bay Trail" and "Braswell" families.
: On many Bay Trail devices, this controller manages the MicroSD slot. A faulty driver will disable the card reader. Find the device SDHB or SDHC and ensure
For older versions like Windows 7, finding a 32-bit driver for this specific hardware can be difficult, as these platforms were primarily designed for 64-bit Windows 8.1 and 10. Key Takeaway
The "8086" prefix is the PCI Vendor ID for Intel Corporation, confirming this is indeed an Intel device.
: 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 Understanding the syntax of an Advanced Configuration and
Run the installer and restart your computer. In many cases, this will automatically resolve the "Unknown Device". 2. Install the Intel Serial IO Driver
Expected status: 15 (present, enabled, shown, functioning).
: 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
: 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.
The most interesting feature of the is its "dual identity" in system firmware, which often leads to a tech-support mystery for Linux users:
