BIOS together with EC firmware for an HP laptop on Quanta board DA0X21MB6D0, revision D, the AMD processor version, marked as confirmed working. The 9.24 MB RAR should hold the system BIOS image and the embedded controller code, which may need writing to separate chips or regions. Quanta uses the DA0 prefix with a project code. Back up the original flash contents before programming, confirm revision D on the PCB, and check that each file matches the size of its target chip.
