BIOS image for the Esonic H55MAL3 desktop motherboard, packed in a RAR archive of 746 KB, with the name indicating a 2MB flash capacity. The H55 in the model name points to an Intel H55 chipset board. A technician would extract the image and write it to the SPI chip with a programmer such as a CH341A when the board fails to POST after a corrupted update. Read and save the original chip contents first, and confirm the chip is 2MB, since an image of the wrong size will not fit or verify correctly.
