Understanding Lenovo OEM Logo BMP 120x120 Patched Files: Customizing Your System Boot
To ensure your custom image is accepted by patching tools, it must meet these strict criteria: Exactly 120 pixels wide by 120 pixels high.
Risks and limitations
Enthusiasts have reverse-engineered Lenovo’s flashing utilities. A "patched" WinFlash64.exe bypasses the signature check. It allows you to flash a modified BIOS .CAP or .ROM file that contains your custom 120x120 BMP, even though the digital signature is now invalid.
: Use a software dump tool or a hardware programmer (like a CH341A) to read your current BIOS ROM.
Most Lenovo BIOS chips prefer indexed color palettes over 24-bit TrueColor.
The most common way to "patch" the logo is by using the official Lenovo BIOS Update Utility Download and Extract:
The real villain is and BIOS digital signing . Lenovo’s BIOS updaters ( WinFlash64.exe or the $0A82000.fl1 files) contain cryptographic signatures. If you attempt to swap the OEM logo using a hex editor without resigning the file, the BIOS flasher will reject the update with an error like:
: A resolution of 120x120 pixels is a common legacy standard for sub-logos or companion icons (such as Energy Star, Intel/AMD badges, or secure boot indicators) displayed alongside the main Lenovo text.
Usually 24-bit or 8-bit indexed color, depending on the motherboard's age.

Check the text documentation ( .txt readme file) included with your specific BIOS utility to find the exact filename string required.
