If you’ve ever wanted to replace that default motherboard logo that flashes when your PC starts, AMI Change Logo is the little utility that makes it possible.
Developed by American Megatrends, it’s a lightweight Windows tool designed to extract and replace the boot logo image inside AMI BIOS or UEFI firmware files.
It doesn’t need coding skills or deep BIOS editing — you just load the BIOS file, pick a new image, and the tool handles the rest.
For modders, small PC brands, or anyone who wants a custom splash screen, it’s one of the easiest ways to personalize a system at firmware level.
Technical Overview
| Attribute | Detail |
|————|———|
| Platform | Windows |
| Purpose | Replace or extract boot logos in AMI BIOS/UEFI images |
| Interface | Graphical (simple point-and-click) |
| Supported BIOS Types | AMI Aptio IV and Aptio V |
| Supported Formats | .BMP, .JPG, sometimes .GIF depending on firmware |
| License | Proprietary (AMI) |
| Risk Level | Moderate — improper image size or format can corrupt BIOS |
| Best Use Case | Custom branding, visual customization, or firmware modding |
What It’s Like to Use
The interface couldn’t be simpler. You open your BIOS file (.ROM, .CAP, or .BIN), and AMI Change Logo immediately scans for embedded images.
Usually, you’ll see one or more splash screens — sometimes vendor logos, sometimes just a blank placeholder.
You can export the existing image to check its size and color depth, then import your own — ideally the same resolution and format.
Once you save the modified BIOS, it’s ready to flash using the manufacturer’s update utility or a tool like AFUWIN or Intel FPT.
It’s not flashy software — more like a single-purpose workshop tool — but it does its job with almost zero fuss.
Typical Workflow
1. Download AMI Change Logo (usually included in AMI’s internal toolkit or shared via OEM channels).
2. Launch the program in Windows.
3. Open your BIOS image file (.ROM, .CAP, .BIN).
4. The tool lists available logo images found inside.
5. Export the original image (optional) to match size and format.
6. Import your new image (.BMP or .JPG) with the same resolution.
7. Save the modified BIOS file.
8. Flash it back using a safe and verified flashing method.
Where It’s Commonly Used
– OEMs replacing vendor logos with custom branding.
– Enthusiasts customizing boot splash screens.
– Small PC builders adding product or company logos.
– Educational BIOS projects or training environments.
– Testing visual elements in preproduction firmware builds.
Important Warnings
– Always back up your BIOS before saving any modified image.
– Make sure the new logo matches the original’s size and color format — mismatches can cause flashing errors.
– Some newer Aptio V BIOS files use compressed or protected regions that AMI Change Logo can’t modify.
– Avoid editing multiple logos unless you’re certain which one is displayed at boot.
– The tool doesn’t verify checksums or image alignment — double-check results with a hex viewer or BIOS unpacker if you’re unsure.
