BIOS and keyboard EC firmware for the Quanta board DAG75AMBAD0, revision D, in a 14.8 MB RAR. The KBEC part is firmware for the embedded keyboard controller, which handles power-on, battery charging and keyboard functions, while the BIOS image goes to the main SPI chip. Quanta boards use the DA...MB...0 numbering pattern. Before flashing with a programmer, confirm Rev D on the PCB, back up both original chips and check each image size against its flash device.
