HP notebook BIOS and EC firmware for Quanta board DAAX3MB16A1, revision A, with a 4 MB BIOS image, marked as tested and working, in a 1.63 MB RAR. DA-prefixed numbers follow the Quanta scheme, and AX3 is the project code behind several HP Pavilion and Compaq models. Providing the EC image alongside the BIOS helps when the laptop has power or charging faults caused by corrupted controller firmware. Back up both chips before programming and check that the image sizes match the actual flash devices on the board..
