Archive for an H61 chipset motherboard identified only as X1, marked OK tested with a note of 8 GB memory support. The 3.00 MB RAR does not name the board maker, so match it carefully to your board. Contents are likely a BIOS image for the SPI flash, used for recovering boards with no POST or corrupted firmware. Read and store the original chip before writing, confirm the chip model and capacity, and verify the image size matches before programming.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @hrtechno. Enginerys does not host this file.
