Archive for the Dell Inspiron 14R 7420 on Quanta board DAORO8MB6E2, revision E2, packed into 3.79 MB RAR; the name does not reveal whether it holds a schematic, boardview or BIOS. The code follows Quanta DA-MB numbering, with the RO8 project appearing written with a letter O, which on the PCB may read R08. Open the archive to identify the contents, then use them to trace circuits or reflash the SPI chip as appropriate. Match the board code and E2 revision before relying on anything inside.
