BIOS dump for a CQ43 notebook, naming the board project CHICAGO_HR_HPC with PV_MB_V1, which reads as the production-version mainboard, version 1. The 4 MB size fits a 32 Mbit SPI flash. The project code name is useful when matching the image to a board, because the silkscreen often shows it alongside the board number. Read and save the original chip with a programmer, confirm the project name and capacity, then write and verify the file.
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 @bios_laptop. Enginerys does not host this file.
