HP Omen firmware archive tied to the Quanta-numbered board DAG3EMB8D0, labelled as an outimage. Outimage files are normally full SPI flash images ready to be written with a hardware programmer, as opposed to vendor update capsules. The RAR is 7.76 MB, so extract it and compare the image size with the flash chip before writing. The DA...MB... pattern identifies Quanta as the board maker. Save a backup of the original chip first, since it holds unit-specific data such as serial and system IDs.
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 @hrtechno. Enginerys does not host this file.
