Change BIOS Logo (AMI ChangeLogo)

SECO x86 platforms display a logo during boot by default. There are typically two logos:

  • Splash logo: large centered image when Quiet Boot is enabled
  • Small logo: small image (top-right) when Quiet Boot is disabled

This guide explains how to replace or remove those logos using the AMI ChangeLogo utility.

Compatibility note

ChangeLogo and BIOS Guard are not compatible.
BIOS Guard is a security feature available on Intel Core platforms. If your platform uses BIOS Guard, do not use ChangeLogo.

Where to get the ChangeLogo utility​

ChangeLogo is included in the BIOS Tools package and can be downloaded from each x86 product page.

The utility is provided as:

  • ChangeLogoWin.exe (Windows 32-bit)
  • ChangeLogoWin64.exe (Windows 64-bit)
If the tool is not available for your platform

For platforms where ChangeLogo is not part of BIOS Tools, custom logo support is available via a SECO support ticket under “Custom BIOS”.

Before you start​

Important

This tool modifies the BIOS binary. After generating the new BIOS file, update the module using the official BIOS update procedure for that product.

Requirements​

  • Windows PC (32-bit or 64-bit) with Command Prompt
  • Original SECO BIOS binary (input)
  • Your replacement image(s)
Image requirements
  • The image must be bitmap (BMP) format.
  • Required sizes:
    • Splash logo: 480×360
    • Small logo: 160×120

Replace BIOS logo(s)​

  1. Copy into the same folder:
    • ChangeLogoWin(.exe/.64.exe)
    • the original BIOS binary (input file)
    • your BMP image file(s)
  2. Open Command Prompt and cd into that folder.
ChangeLogoWinYY /i inROMFile /o outROMFile /r logofile [/f]
ChangeLogoWinYY /i inROMFile /o outROMFile /r logofile /s [/f]

Where:

  • YY = "" (32-bit) or 64 (64-bit), depending on the tool you downloaded
  • /i = input BIOS binary
  • /o = output BIOS binary that will be generated
  • /r = replacement image file (BMP)
  • /s = select small logo (omit for splash)
  • /f = force destination file overwrite (optional)
Next step

Once you see a success message, flash the output BIOS binary using the product’s BIOS update procedure (AFU or BGT, depending on the platform).

Remove BIOS logo(s)​

  1. Open Command Prompt and cd into the folder containing the tool and BIOS binary.
ChangeLogoWinYY /i inROMFile /o outROMFile /d [/f]
ChangeLogoWinYY /i inROMFile /o outROMFile /d /s [/f]

Where:

  • /d = remove the logo from the BIOS binary
  • other parameters are the same as in the replacement commands

Troubleshooting​

The output BIOS file is not created​

  • Ensure you have write permissions in the folder (try C:\Temp).
  • Add /f if the output file already exists.

The tool reports image errors​

  • Confirm the image is BMP (not PNG/JPG renamed).
  • Confirm the required size: Splash 480×360, Small 160×120.

Platform uses BIOS Guard​

  • Do not proceed with ChangeLogo. Open a SECO support ticket under Custom BIOS.
