The ATI 4379 Serial ATA Controller driver helps Windows communicate with SATA storage devices connected through this ATI controller. Although ATI is often associated with graphics hardware, this device is a storage controller, not a GPU, so it requires a storage driver rather than a display driver.

Key Features

• SATA storage communication: Provides the interface Windows needs to send and receive data through the controller to attached SATA drives.
• Device identification: Helps Windows recognize the ATI 4379 Serial ATA Controller and display its status in Device Manager.
• Storage operation support: Enables the operating system to manage connected storage through the controller’s supported functions. Available capabilities depend on the hardware and driver package.
• System-specific compatibility: A correctly matched driver supports reliable operation on the intended Windows version and system architecture. Do not assume a legacy package supports every newer release of Windows.

How to Install

1. Confirm your hardware and Windows version. Open Device Manager and locate the controller, which may appear under Storage controllers, IDE ATA/ATAPI controllers, or Other devices. Check its hardware IDs under Properties > Details, then confirm whether your system uses a 32-bit or 64-bit edition of Windows.

1. Check the package’s compatibility. Before downloading, verify that the driver explicitly supports your controller and operating system. For Windows 11, 10, 8, or 7, compatibility must be confirmed individually; the device name alone does not establish support. Prefer a package validated by your computer or motherboard manufacturer.

1. Prepare for the update. Back up important files and create a restore point if System Protection is enabled. Storage drivers can affect startup, especially when the Windows drive is connected to this controller. Avoid changing SATA or RAID settings in the BIOS during installation.

1. Install the matching driver. Run the package’s installer if one is included. Otherwise, extract the download, right-click the controller in Device Manager, select Update driver, and choose Browse my computer for drivers. Point Windows to the extracted folder and follow the prompts. Do not force an incompatible driver to install.

1. Restart and verify. Reboot if prompted, then check Device Manager for warning icons and confirm that your connected drives remain accessible. If the update causes problems, use Roll Back Driver when available or restore the previous working configuration.

Common Issues and Fixes

• Install fails or driver is rejected: Old ATI 4379 packages may lack modern signing. Use Device Manager → Update driver → Browse my computer, point to the extracted INF, and run setup in Windows compatibility mode for the driver’s original OS. Verify the Hardware ID (`PCIVEN_1002&DEV_4379`) before installing.
• Device not detected: Confirm the SATA controller is enabled in BIOS/UEFI and check whether ports are set to IDE, AHCI, or RAID. The 4379 driver must match the current BIOS mode; changing modes after Windows installation can hide the device or cause boot errors.
• Version conflicts/yellow bang: Remove any generic Microsoft `storahci`/`amd_sata` or previous ATI package, reboot, then install the matching AMD/ATI chipset SATA driver. If Windows reinstalls the inbox driver, use “Roll Back Driver” or select the specific INF manually.
