BIOS and EC firmware set for the Quanta board DASS8BMBAE1, revision E, in a 2.26 MB RAR. Quanta uses the DAxxxxMB naming and builds boards for several laptop brands, so the PCB code is the reliable identifier. Having both images lets you restore the system BIOS and the embedded controller firmware, which handles power-on, charging and keyboard functions. Program each chip with an SPI programmer. Dump the originals first and confirm the revision letter on your board matches.
