BIOS dump for the MSI H81M-P32 desktop motherboard, built on the MSI MS-7846 platform, with firmware version 160 in the MS-7846.160 naming and sized for an 8MB flash chip. The RAR archive needs extracting before use. MSI reuses the MS-7846 board number across many H81, B85, H87 and H97 micro-ATX variants, so confirm the exact model printed on the PCB. Read and save the original SPI chip contents with a programmer before writing, and make sure the image size matches the 8MB chip fitted.
