BIOS archive for the board code-named PETRONAS-14, with a PM suffix whose meaning is not stated in the name. The RAR package is 2.08 MB and should contain a flash image for direct SPI programming. Codenames like this come from ODM development projects, so check the silkscreen on the PCB for the same name before use. Back up the original chip with a programmer, confirm the image matches the chip capacity, and then write and verify. It is suitable for recovering a corrupted or failed BIOS.
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 @afsbiosfree. Enginerys does not host this file.
