The MSI MS-7533 board number is all the name of this 958 KB ZIP file reveals; revision and contents are not given. At under a megabyte it may hold a BIOS image, a boardview or a few schematic sheets, so open it and sort out what is there. A boardview opens in OpenBoardView or a similar viewer for locating components and nets, while firmware is written with an SPI programmer after you save the original chip. MSI prints MS-7xxx codes and revisions on its PCBs, so check the marking first.
