BIOS for MSI board MS-7869 version 1.0, read from chip U41, a Macronix MX25L6473E, which is an 8 MB (64 Mbit) SPI flash, archived as a 2.97 MB RAR. Knowing the reference designator and chip type helps locate the flash on the board and select the right device in programmer software. Use a CH341A or similar programmer to write it, after first reading and saving the existing contents. Check that the board revision matches and the unpacked image is exactly the chip size.
