Firmware for the Dell Vostro 5470 on Quanta board DAJW8CMB8E1, revision E. The DA-prefixed code is Quanta's numbering, identifying Quanta as the ODM for this ultrabook board. The 3.46 MB RAR is used to reprogram the BIOS flash when a unit fails to post, loops on power or was bricked by a bad update. Check that the board revision on the PCB is E, back up the original chip with a programmer before writing, and verify that the image size fits the flash capacity fitted to the board.
