BIOS image for the Esonic HM65-BTC-COMBO board, version or revision P2, sized for a 4 MB flash chip according to the name. The HM65 token points to the Intel HM65 mobile chipset this board uses. A dump like this is written to the SPI chip with a programmer when the board shows no display or fails to POST after a bad flash. Unpack the RAR, confirm the image is exactly 4 MB to fit the chip, and keep a copy of the original contents before erasing anything.
