BIOS and EC firmware package for a Z480 laptop on board DALZ2AMB8F0, revision F, in a 2.66 MB RAR archive. The DA-prefixed code follows Quanta's board numbering, with LZ2 as the project code; Quanta designs and builds the board. Including the embedded controller firmware matters because power-on and charging faults can stem from a damaged EC image as well as from the BIOS. Flash with an SPI programmer after reading and saving the original chips, and confirm both the board number and Rev F on the PCB beforehand.
