Quanta DAH98PMBAB0 revision B HF BIOS image for a 16MB flash chip, stored in a ZIP archive of 5.74 MB. No laptop brand or model is given, so the DA-coded number printed on the motherboard is the only safe way to match it. Quanta's DAxxxx numbering identifies board design and revision. Technicians use such images to rescue boards with corrupted firmware via a CH341A or similar SPI programmer. Back up the existing chip first and confirm it is 16MB, since other uploads for this board may differ in content.
