BIOS image for the MSI Z390-A PRO desktop motherboard, sized for a 16 MB flash chip according to the name, in an 8.12 MB RAR. This Intel Z390 board stores its firmware on an SPI chip that can be rewritten with a programmer when the board no longer posts. Confirm the chip capacity is 16 MB so the image fits. Read the original chip before writing to preserve the MAC address and serial, and note that a full dump includes the ME region, which may need to match the board.
