BIOS archive labelled for the HP Zed Air XU133U at board revision 2.1, filed under Quanta board number DA0U83MB6E0, with an OK mark suggesting the dump was confirmed working. The RAR is 6.79 MB, so unpack it and inspect the image before use. Quanta prefixes its motherboards with DA0, and the code silkscreened on the PCB should match before you write anything. Read and save the original SPI chip with a programmer first, and make sure the image size equals the flash chip capacity, otherwise it will not fit.
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.
