BIOS image for an XTHERION H81XT-4TA desktop motherboard, an Intel H81 chipset board marked China in its name, with a 4MB flash size, compressed into a 3.14 MB RAR. Such a dump is used to recover the board after a failed update or corrupted SPI flash by writing it with a programmer such as a CH341A. Read and store the original chip contents first, confirm the board code on the PCB matches, and ensure the extracted image is exactly 4 MB for the chip.
