HP motherboard firmware package for the Quanta board DAG3DDMB8C0, with the code 08574 in the name, holding the BIOS image together with ITE embedded controller firmware. ITE EC chips manage power sequencing, battery charging and keyboard, so a damaged EC image can leave a laptop dead. Quanta boards follow the DA plus project code pattern, here G3D. Match the PCB number before use, dump and save the existing SPI and EC contents, and check that image sizes fit the target chips.
