BIOS archive for the HP ProBook 4430s built on motherboard 6050A2465101, revision A02 as given in the name. The 6050A numbering belongs to Inventec, the ODM behind many ProBook boards. Packed as RAR at 2.42 MB, it is meant for reflashing the SPI BIOS chip with an external programmer such as a CH341A when the laptop shows no POST or a corrupted firmware. Confirm the PCB number and revision match, read and save the original chip contents first, and verify the image size equals the chip capacity before writing.
