BIOS dump archive for the HP Pavilion 15-ab524TX, linked to the Quanta-style board number DAX1BM1AF0 and project code X1B. The TX suffix in HP model names usually indicates discrete graphics. DA0 prefixed numbers are typical of Quanta-made boards. Use the image to reprogram a corrupted SPI flash with an external programmer when the laptop shows no display or loops on power-up. Before writing, back up the existing chip, which stores serial and product data, and check the board marking matches DAX1BM1AF0.
