BIOS firmware archive in RAR format for a board with the LAIKA project name and the number 6050A3156701-MB-A01, revision A1. The 6050A prefix follows the Inventec numbering pattern. Expect an SPI flash image inside, used for reprogramming the BIOS chip with a hardware programmer such as a CH341A when a laptop is dead or stuck after a corrupted update. Back up the original chip contents first, check the board number and revision on the PCB, and make sure the image size matches the flash capacity.
