BIOS and EC firmware set for Quanta board DAZRQMB18F0, in a 3.43 MB RAR. No laptop brand or model is given, so identify the machine from the label on the PCB. The DA prefix and layout follow Quanta's board numbering, and the trailing digits encode the revision. The EC image controls power sequencing, charging and keyboard functions, while the BIOS image goes to the SPI flash. Back up both chips with a programmer before flashing, and check each image matches its target chip's capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
