RAR archive of about 745 KB with firmware for the Quanta DAQT8HMB6B0 motherboard, the QT8 project. The name gives no laptop brand, model or revision, although this board number is associated with HP dv5 machines. Quanta's DA...MB numbering identifies the ODM board, which should match the silkscreen on the PCB. The contents are likely a BIOS image for external programming. Back up the original flash, then check that the extracted file size matches the chip before writing.
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.
