Firmware archive for the MSI MS-7392 mainboard, a 382 KB RAR with no version or revision stated in the name. It most likely contains a BIOS image for writing to the board's SPI or LPC flash chip with an external programmer when an update failed or the board shows no POST. MSI desktop boards carry the MS number on the PCB, so match it and the revision before use. Always read and keep a copy of the existing chip contents, and confirm the image size fits the chip.
