RAR archive of roughly 760 KB covering the ECS 661FX SF2 motherboard at revision 2.2. The file name gives no detail of the contents, so extract it and check whether it holds a schematic, BIOS image or both. The 661FX naming refers to the SiS 661FX northbridge platform. Revision 2.2 may differ from earlier 661FX SF2 boards in components and routing, so match the silkscreen revision before using it for diagnosis or reflashing.
