The keyword lenovo oem logo bmp 120x120 patched is more than a search query—it is a badge of honor among low-level PC modders. It represents the fight against corporate brand ubiquity, the willingness to risk a bricked motherboard for aesthetic purity, and the technical know-how to reverse-engineer a decade-old BIOS restriction.
While the days of 120x120 are fading, the methods pioneered by this community—signature bypasses, UEFI module replacement, and checksum patching—remain relevant for modern firmware hacking. Whether you are maintaining a fleet of legacy Lenovo devices or simply want to see your family photo for the two seconds before Windows loads, the patched 120x120 BMP is your gateway.
Final Advice: Join forums like Win-Raid or BIOS-Mods before attempting this. Download verified patches. And always, always back up your original BIOS twice.
The word patched is the linchpin of the entire operation. It refers to three possible modifications:
Many industrial machines, medical carts, and kiosks run on older Lenovo ThinkCentres (M73, M93p) or ThinkPad X220/T420 series. These systems have no official support for custom boot logos. The 120x120 patched method is the only way to replace the logo on such hardware.
The search query "Lenovo OEM logo BMP 120x120 patched" refers to a specific technical process used by IT professionals and computer enthusiasts to customize the boot screen (splash screen) on Lenovo computers. This process involves modifying the BIOS or UEFI firmware to display a custom image—typically a company logo—instead of the standard Lenovo branding when the computer is turned on.
Here is a breakdown of the technical components involved:
Using tools like UEFITool, PhoenixTool, or InsydeFlash, modders extract the LOGO module from a stock BIOS, replace the embedded bitmap, and then "patch" the module’s checksum. This creates a patched BIOS file—one that is functionally identical to the original except for the logo. lenovo oem logo bmp 120x120 patched
Many Lenovo laptops/desktops store the OEM boot logo as a 120×120, 24-bit BMP inside a protected BIOS region. The official flashing tools reject modified logos due to checksum or signature mismatches. Users want to personalize the boot screen without bricking the system.
The phrase "Lenovo OEM logo BMP 120x120 patched" signifies a workaround solution for branding hardware. It represents a modified bitmap image file, stripped of standard headers and compressed to fit strict legacy firmware constraints, allowing a third-party logo to replace the manufacturer's default boot screen.
Customizing your Lenovo boot splash screen is one of the coolest ways to make your hardware truly yours, but getting that 120x120 patched BMP just right requires a bit of technical finesse. Whether you're looking to swap the standard red logo for a vintage "Legend" aesthetic or a personalized "Lenowo" meme, here is everything you need to know to pull it off safely. 🛠️ The "Pro" Customization Guide
To successfully patch your Lenovo OEM logo, you must adhere to strict formatting rules. Modern ThinkPads and IdeaPads are notoriously picky about image size and color depth.
This modification leverages built-in BIOS/UEFI support for user-defined startup images.
File Specifications: The "120x120" refers to the resolution of the image in pixels, while ".bmp" denotes the Bitmap (Windows) file format .
Color Depth: These logos are typically limited to 16 colors (4-bit) or indexed color modes to ensure compatibility with legacy BIOS environments . The keyword lenovo oem logo bmp 120x120 patched
Size Constraint: To fit within small firmware storage regions, the image file size is often strictly limited, frequently to under 30KB or 60KB depending on the model generation .
"Patched" Status: This indicates the image has been processed or integrated into the BIOS update package using tools like WinFlash64.exe or winuptp.exe with specific parameters (e.g., -patch -logo) to replace the default Lenovo OEM branding . Implementation Methods
Users typically apply these patched logos through two primary avenues: Lenovo UEFI Boot Logo Changer - GitHub
To update or "patch" a Lenovo OEM boot logo using a custom 120x120 BMP file, you must use Lenovo's official BIOS update utility or third-party tools like the Lenovo UEFI Boot Logo Changer. Requirements for the Logo File Format: Windows Bitmap (BMP) or sometimes GIF/JPG.
Color Depth: Historically required to be 16-color or 16-bit depending on the specific BIOS generation. File Size: Typically must be under 30KB to 60KB total.
Dimensions: While 120x120 is standard for some legacy systems, modern UEFI systems often support larger images (up to 40% of the screen resolution). Step-by-Step Patching Process
Extract BIOS Utility: Download the BIOS Update Utility for your specific model from the Lenovo Support Site. Run the .exe but select "Extract Only" instead of installing. Prepare the Image: Save your 120x120 image as LOGO.BMP. The word patched is the linchpin of the entire operation
If using older tools, you may need to run LOGO.BAT (found in the extracted folder) to compress the bitmap into a LOGO.MOD file.
Place the File: Move your LOGO.BMP (or LOGO.JPG/LOGO.GIF) into the extracted BIOS folder (e.g., C:\DRIVERS\FLASH\[Version]). Flash the Logo:
Windows: Run winuptp64.exe as Administrator. The utility should detect the custom image and ask: "A custom start up image file was found. Do you want to apply it?" Click Yes.
Command Line: Alternatively, use WinFlash64.exe -patch -logo LOGO.BMP from an elevated command prompt.
Reboot: The system will reboot and flash the BIOS. Your patched logo will appear during the next startup.
Caution: Ensure "BIOS Back Flash" is enabled in your BIOS settings if you are flashing the same version already installed on your machine. Lenovo UEFI Boot Logo Changer - GitHub
Here’s a draft of a software feature specification for “Lenovo OEM Logo BMP (120x120) Patched” — suitable for a BIOS modding tool, boot animation patcher, or custom firmware utility.
Lenovo firmware often requires the logo to be 120x120 pixels. While the screen resolution is much higher, the firmware sometimes uses a smaller "thumbnail" or splash image stored in a specific BIOS region.
