BIOS dump for the HP 15-bc438ur laptop on board DAG35NMB8C0, supplied as a 14.0 MB RAR archive. The DA-prefixed number follows Quanta numbering, so Quanta is the ODM behind this HP board. Use it to reprogram the flash with a hardware programmer on a unit that fails to post. HP firmware stores serial and product data, so read and keep the original first. Verify the board number and revision on the PCB and ensure the image size matches the chip.
