: Select the target image (often named MyOemLogo1 ) and click "Replace Logo".
: Use a flash utility like AFUWIN to write the modified image back to the motherboard. Note: Modified BIOS files often lose their digital signature, which may prevent them from being flashed via standard built-in motherboard utilities (like MSI M-Flash). Risk Assessment & Common Issues Modifying BIOS firmware carries significant risks:
: Modern motherboards often use Secure Flash , which checks for official digital signatures. Modifying the logo breaks this signature, frequently causing errors like "Secure Flash Rom Verify fail" or "ROM Layout mismatch" during flashing. ami changelogo tool v5.0.0.2
Disclaimer: Modifying BIOS firmware carries inherent risks. An incorrect flash can render hardware inoperable. Always ensure you have a backup BIOS chip or recovery mechanism before proceeding.
Lastly, possible alternatives. If someone is looking for similar tools for different BIOS manufacturers, that could be a section to add. But again, since the user asked specifically about AMI's tool, maybe stick to that unless alternatives are relevant. : Select the target image (often named MyOemLogo1
Many modern motherboards (2020+) have Secure Flash or BIOS Guard that rejects any checksum-modified firmware, even if the tool says it’s correct. Solution: Disable BIOS Write Protection and Secure Boot temporarily in the BIOS settings before flashing. After the flash, re-enable them.

: Your custom image usually needs to be a JPEG or BMP and often must not exceed a resolution of 800x600 .
