Original BIOS dump attributed to Lenovo, 4.00 MB, with no model or motherboard number given in the name, so its target board cannot be identified from the name alone. The org marker typically means an unmodified read. The size fits a 32 Mbit SPI flash chip. Before flashing with an external programmer, compare the chip capacity, board markings and any internal strings viewed in a hex editor, and save the existing chip contents so the board can be returned to its prior state.
