Original BIOS backup taken from an ASUS H81M-C desktop motherboard, an Intel H81 chipset board, stored in a 3.56 MB RAR. Being a read of a working board, it is meant for restoring a corrupted or failed SPI flash with a programmer such as a CH341A. A dump read from another unit carries that board's serial, MAC address and possibly settings, which may need adjusting. Save the contents of your own chip before writing, and confirm the image size matches the flash capacity or it will not fit.
