Archive for the ECS 661FX SF2 board, revision 1.0, size 754 KB, tagged as copy (2). It belongs to the 661FX family, but the SF2 variant should be told apart from the 661FX-M by checking the PCB silkscreen. The contents are not described, so extract it with 7-Zip or WinRAR. Schematics inside would help with tracing rails and signals. A BIOS image would be written with an external programmer after backing up the original chip. Make sure the image size matches the flash chip capacity.
