Medion: B460h6em Bios Update Fix

Medion B460H6EM BIOS Update — Fix Guide

Summary

This guide shows how to update the BIOS for a Medion B460H6EM motherboard to resolve firmware-related issues (boot problems, hardware compatibility, microcode/CPU support, stability). Follow steps carefully — incorrect BIOS flashing can brick your board.

Tools required:

1. Download AFUWIN 5.12 or AFUWIN 4.08 (not the latest version).
2. Open Command Prompt as Administrator.
3. Navigate to the folder with AFUWIN.exe and your BIOS .ROM file.
4. Run the unlock command first:
   AFUWIN.exe /OEMSMI:23 (This unlocks the OEM system management interface).
5. Then flash with verification disabled:
   AFUWIN.exe BIOS.ROM /P /B /N /K /R /L /E /X

• The B460 chipset natively supports 10th Gen CPUs. However, to support 11th Gen CPUs (e.g., i5-11400F), a specific BIOS update is required. Without this update, the system will not POST (Power On Self Test).
