Replacing the motherboard logo ROM requires careful handling to avoid bricking your system. Follow these essential steps:
Essential Preparations
Requirements:
- A compatible motherboard (check OEM support).
- The exact original BIOS ROM file for your motherboard (download from official support site).
- A dedicated logo ROM replacement/modification tool specific to your motherboard brand (e.g., AMIBCP for AMI BIOS).
- A compatible replacement image file (common formats: BMP; check required resolution, bit-depth, and compression).
Critical First Step: Backup your current BIOS ROM file using the official OEM tool or a reliable third-party utility before any editing.

Replacement Procedure
- Identify Logo Module: Open the original BIOS ROM file in your chosen tool. Locate the specific module housing the boot logo (often named "Logo", "OEM Logo", or similar).
- Prepare Replacement Image: Convert your desired logo to the exact format, resolution, color depth (often 24bpp), and compression required by the motherboard. Resize precisely using an image editor.
- Replace Module: Within the tool, select the identified logo module and replace it with your prepared image file. Some tools offer direct "replace" functions, others require extracting the image, replacing it externally, and re-inserting.
- Save Modified ROM: Save the edited BIOS ROM file under a new, distinct filename.
- Flash Carefully: Use the OEM's official BIOS flashing utility (often executable from within the OS or BIOS/UEFI environment) to flash the modified ROM file onto the motherboard. Ensure stable power (laptop: fully charged + plugged in; desktop: use UPS).
Critical Warnings
- RISK OF BRICKING: An incorrect ROM flash can render the motherboard unusable.
- Model Specificity: Use the ROM file and tool explicitly matching your motherboard model and BIOS version.
- Image Compliance: Non-compliant images cause flashing failure or corruption.
- Power Stability: Any interruption during flashing will likely brick the board.
Consult your motherboard manufacturer's technical support documentation for model-specific guidance and approved tools.
