Firmware package with main BIOS and KBEC keyboard/embedded controller images for board 6050A2677201, revision A01, project SNOWI20, in a 5.56 MB RAR. Pairing both dumps allows recovery of laptops with no power, no boot or keyboard and charging faults tied to the EC. The 6050A prefix follows the Inventec numbering pattern. Confirm the full number and A01 revision on the PCB, read and keep the original chip contents with a programmer, and check each image size against the flash it is destined for.
