Firmware file for an MSI B85M Night Elf board, MS-7823, labelled vH4 in the name. The RAR archive is about 7.76 MB and is expected to contain a BIOS image for the motherboard SPI flash. Because MSI reuses the MS-7823 number across several B85M versions, confirm the model printed on the board and the PCB revision before writing. Technicians typically program such an image with a CH341A or similar device when the board fails to post after a bad update; save the original contents and check chip size first.
