RAR archive of about 6.5 MB for the Lenovo V530s with tokens 071CR and IB365CX, the latter likely the motherboard code, though the name does not state what files are inside. Packages tagged with a board code like this usually carry a firmware dump or service files, so inspect them before use. When it holds a BIOS image, back up the existing SPI chip with a programmer first and confirm the board marking matches the IB365CX code. A copy suffix in the name suggests a duplicate, so compare it with other versions you may have.
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 @hrtechno. Enginerys does not host this file.
