ZIP firmware package for a mainboard designated CHICAGO BR HPC MV MB V1; the device brand and model are not stated in the name. Board code names like this are often used by ODMs, with V1 likely marking the first board version. Extract the archive to see whether it contains a BIOS or EC image and check its size against the flash chip. Match the markings on the board, then read and keep the original chip contents before writing the dump with an SPI programmer.
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.
