Archive for a board labelled H61FFL ES, revision 1.0, with the note unknown, suggesting the exact maker or source was not identified. At about 2.3 MB it most likely holds a BIOS image for an H61 platform board, but verify the contents after extraction. Because the origin is uncertain, compare the board silkscreen and revision carefully before using it. Read and save the original SPI chip with a programmer first so the board can be restored if the image does not work.
