The Foxconn BIOS 45CM BIOS 45CM K BIOS 45CM S BIOS 45GM download listing covers several Foxconn motherboard identifiers, so check your exact model before choosing a driver. For this Audio category, the driver’s role is to help Windows communicate with the board’s onboard sound hardware for playback and recording—not to update the BIOS.

Key Features

• Onboard audio support: Enables Windows to use the motherboard’s integrated audio hardware when the package matches its audio controller.
• Playback and recording: Supports compatible speakers, headphones, and microphones through the audio connections available on your board.
• Windows sound integration: Allows recognized audio devices to appear in Windows sound settings, where you can select playback and recording defaults.
• Troubleshooting support: Installing the correct driver may resolve missing audio devices or driver-related sound problems. Available controls depend on the audio chipset and package.

How to Install

1. Identify your motherboard and audio hardware. Confirm whether you have a Foxconn 45CM, 45CM K, 45CM S, or 45GM board using its printed model label or system documentation. If necessary, check the audio controller’s hardware IDs in Device Manager.

1. Check operating system compatibility. Match the download to your Windows version and system architecture. Although Windows 11, 10, 8, and 7 are listed for this page, that does not establish that one package supports every version; verify the package’s stated requirements before installing.

1. Download and prepare the audio package. Save the matching driver locally and extract it if it is compressed. Close audio applications and consider creating a restore point. If the download contains BIOS flashing tools rather than an audio installer, do not use it to fix sound issues.

1. Install the driver. Run the included setup program and follow its prompts. If the package provides driver files without an installer, open Device Manager, select the relevant audio device, choose Update driver, and browse to the extracted folder.

1. Restart and test sound. Reboot if requested, then open Windows sound settings to choose the correct output and input devices. Test playback and microphone recording. If sound remains unavailable, check cable connections, mute settings, and whether onboard audio is enabled in the motherboard’s firmware settings.

Common Issues and Fixes

• BIOS flash fails or board won’t boot: Confirm the exact model string—45CM, 45CM K, 45CM S, or 45GM—before flashing. Use Foxconn’s utility and a FAT32 USB drive; do not cross-flash between variants. If interrupted, clear CMOS and retry only with the correct file.
• USB drive not detected in BIOS update tool: Use a USB 2.0 port and a small FAT32-formatted drive. Disable fast boot, enable legacy USB support, and place the BIOS file at the root directory.
• Version conflicts or unstable settings after update: Match the BIOS release branch to your board revision, avoid downgrading unless Foxconn documents it, and load optimized defaults after flashing. Recheck CPU/memory settings manually.
