BIOS firmware archive for a laptop mainboard numbered DAG3HDMB8D0, revision D. The DA prefix with MB in the middle follows Quanta's board numbering, so Quanta is the board maker regardless of the laptop brand on the lid. The RAR is 14.8 MB, so it likely holds one or more dumps plus notes; unpack and check the image size against the SPI chip before writing. Confirm the board number and REV D on the PCB silkscreen, read and save the original chip contents with your programmer, then flash and verify the write.
