Lenovo Oem Logo Bmp 120x120 Patched (2027)

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.

| Parameter | Value | |-----------|-------| | Dimensions | 120 x 120 pixels | | Color depth | 24-bit RGB (not 32-bit) | | File size | ~42.2 KB | | Compression | None (uncompressed) | | Orientation | Landscape (120 width, 120 height) |

A patched BIOS will break Secure Boot chain of trust. Windows 11 will no longer boot without disabling Secure Boot or reinstalling with custom secure boot keys. For most users of patched logos, this is an acceptable trade-off. lenovo oem logo bmp 120x120 patched

Cause: The patched BIOS corrupted the boot block. Fix: Solution: Short the system board’s CLR_CMOS jumper

Even with a perfectly prepared 120x120 BMP, things go wrong. Here are the most frequent issues:

Modifying BIOS files carries inherent risks.
