BIOS for HP DV6 and DV7 AMD laptops on Quanta board DA0LX8MB6D1 revision D, project LX89, intended for a 25Q16 flash chip, in a 1.18 MB RAR. DA0xxxMBxxx is Quanta's board-number pattern. A 25Q16 part holds 16 Mbit, or 2 MB, so the image should be that size. Use it to recover a board that powers up without POST by programming the SPI chip externally. Back up the original chip first and check that the PCB is revision D.
