Flash the BIOS

Final BIOS flashing guide

Verify before flashing

The final BIOS is tied to the exact board, revision, and delivery record. Stop if any field differs.

01

Verify the delivered file

Compare the support record with the physical board; do not trust the filename alone.

  • Check brand, exact model, revision, and board ID
  • Check file size, SHA-256, and support record
  • Confirm this is the final BIOS, not the HWID readout BIOS
02

Prepare a FAT32 USB drive

Use a reliable USB drive, format it as FAT32 as required, and keep the BIOS file alone in the root.

  • Prefer a simple, reliable USB 2.0 drive
  • Back up existing USB data before formatting
  • Keep only the required BIOS file in the root
03

Rename only as instructed

Rename the file only when the exact board manual or approved delivery note requires it.

  • MSI commonly uses MSI.ROM
  • GIGABYTE Q-Flash Plus commonly uses GIGABYTE.BIN
  • The exact board manual and delivery note take priority
04

Choose the correct flash path

Rear-panel Flashback and in-BIOS M-FLASH / Q-Flash are different workflows.

  • Rear path: follow the board manual for shutdown and PSU state
  • Menu path: use only when explicitly approved
  • Do not use unknown Windows flashing utilities
05

Locate the dedicated port and button

Insert the drive into the port explicitly marked for BIOS flashing.

  • Find the USB port marked Flash BIOS or BIOS
  • Find the Flash BIOS Button or Q-Flash Plus button
  • Port position and color vary by model
06

Start flashing and wait

Trigger flashing exactly as documented and wait until the board finishes by itself.

  • Do not power off, remove USB, restart, or press the button again
  • Do not interrupt automatic fan or reboot cycles
  • Stop repeated attempts if the indicator is abnormal
07

Check the first boot

Boot only after flashing completes. AMD memory training may make the first boot much longer.

  • Wait for full POST without repeated forced shutdowns
  • Check BIOS version, date, boot drive, and PCIe devices
  • Restore one setting group at a time and preserve error evidence

Never cross-flash models

Stop whenever the model or version differs and ask support to verify again.
