BIOS firmware for the HP Pavilion tx2-1025dx convertible, Quanta board DA0TT3MB8D0 revision D, in an 814 KB ZIP. The DA0 plus project code plus MB format belongs to Quanta, with TT3 as the project code. The small size fits an older SPI flash of about 1 MB or less, so check the chip marking before programming. Writing the dump with an external programmer can revive a board left dead by corrupted firmware. Read and keep the original contents before you erase the chip.
