Dell firmware set for Quanta motherboard DAFM9CMB8C0, revision C, PWB A00, marked as a working BIOS plus EC dump, in a RAR archive of about 7.8 MB. The DA...MB code follows Quanta's numbering, the ODM that produced this Dell board. Use the contents to rewrite the SPI BIOS chip and embedded controller firmware with a programmer when the laptop is dead or stuck. Save a backup of the original flash before writing, and check that each image matches the size of the chip it is going into.
