ECS 661FX SF2 motherboard package for PCB revision 2.2, stored as a 760 KB RAR archive. The name does not specify whether it contains a schematic, a boardview or a firmware image, so inspect it after unpacking. It is the later revision of the SF2 model, and layouts or BIOS builds can differ from rev 1.0. Repair uses include tracing rails, locating the BIOS chip and checking regulators. Confirm that the board is marked rev 2.2, and back up the original chip before flashing anything.
