Working BIOS for a board codenamed LAIKA, number 6050A3202801, revision MB-A02 (A2). The 6050Axxxxxxx pattern belongs to Inventec boards, often used in HP and Dell notebooks, though the brand is not given. The 6.96 MB RAR should contain the flash image; check its size against the SPI chip. Read and save the existing firmware with a programmer before writing, and make sure both the 6050A number and A02 revision on the PCB match.
