Compressed firmware image for a desktop board labelled Q77M_D2H, which points to an Intel Q77 chipset microATX design; the name states no revision. The 4.19 MB archive is likely to contain the full SPI flash contents including descriptor and ME regions. Such a dump is written with an external programmer to fix no-boot faults caused by corruption. Check the board marking and revision on the PCB, save the original chip before overwriting, and confirm the image size matches the installed flash chip.
