Working BIOS image for the ASUS PRIME Z270-P motherboard, revision 1.02, stored in an 8.50 MB RAR archive. Technicians write such a dump to the board's SPI flash with a programmer when the system shows no post, no display or was bricked by an interrupted update. Verify the PCB revision matches 1.02 before use. Read and keep a copy of the original chip first, since it may hold board-specific data such as serial and MAC, and confirm the image size matches the flash chip so it fits correctly.
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.
