If your system isn't recognizing a newly installed NVMe M.2 SSD or an external peripheral, the older BIOS likely lacks the necessary hardware maps.
MSI provides a robust utility called , integrated into the BIOS, which is the safest method to update your BIOS. Phase 1: Preparation
Because the CPU and graphics components are soldered directly to the MS14B31 board, maintaining microcode stability via regular BIOS revisions is crucial to extending the life of the machine. Msi 14 A10ras Motherboard 607-14B31-44S
Locate the flash batch file (typically named flash.nsh , update.bat , or similar) and type its name, then press Enter to execute. ms14b31 bios updated
Browse your FAT32 USB drive, select the updated MS14B31 BIOS file, and confirm the action.
If you previously used custom settings (such as XMP profiles for RAM, specific fan curves, or virtualization options like VT-x/AMD-V), re-enable them now.
The (often referred to as the MS-14B31 ) typically corresponds to specific MSI laptop models like the MSI Modern 14 or Prestige 14 series. Updating the BIOS on these machines is a critical procedure that can improve system stability, hardware compatibility, and security. Essential Preparation Before starting, ensure you have the following ready: If your system isn't recognizing a newly installed NVMe M
If the power cut out or the system froze during the update, the motherboard may be bricked. Check if your specific MS14B31 variation features a physical BIOS recovery button on the back I/O panel or an internal jumper labeled "Clear CMOS." Shorting the CMOS jumper or removing the motherboard coin-cell battery for 5 minutes can sometimes force a reset to a backup factory ROM.
The MS14B31 motherboard—frequently utilized in popular budget-friendly laptops and pre-built mini PCs—is a workhorse component. However, like any foundational hardware, its performance is tightly tethered to its firmware. Keeping your MS14B31 BIOS updated is the single most effective way to resolve mysterious system crashes, unlock compatibility with newer hardware, and patch critical security vulnerabilities.
Re-enter the BIOS menu ( Delete / F2 ) immediately upon reboot. Locate the option to Load Setup Defaults (often F9 ), select it, then save and exit ( F10 ). This clears out old configuration data that could cause instability with the new firmware. Msi 14 A10ras Motherboard 607-14B31-44S Locate the flash
The MS14B31 BIOS update specifically targets a vulnerability identified as CVE-2014-8272. This vulnerability is caused by a weakness in the BIOS's handling of certain types of data, which could allow an attacker to execute arbitrary code on the system.
If you're having trouble finding the right drivers or want to know if a specific software issue is fixed by this update, How to update MSI motherboard BIOS
Grab a stable USB flash drive (8GB or 16GB is ideal). Format it to FAT32 file system, as most BIOS environments cannot read NTFS or exFAT drives.
Unplug the power cable, remove the battery (if applicable), and hold down the physical power button for 30 seconds. Plug it back in and try booting.
