BIOS dump for the Lenovo ThinkBook 14 IIL on Quanta motherboard DALVACMB8D0, revision D, labelled as working and fully tested. The DA prefix with an eight-character code is the Quanta board-number pattern, and the number and revision on the PCB should match before use. Packed as an 8.36 MB rar, the image is written to the SPI flash chip with a programmer to fix no-boot or corrupted firmware. Back up the original chip first to keep serial and system data.
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.
