Archive for the ECS 661FX SF2 board, revision 2.2, packed as RAR at about 760 KB. It appears to be a duplicate copy of another revision 2.2 package of identical size, so one download is likely enough, but compare the contents to be sure. The contents are not named, so extract first. The board uses the SiS 661FX chipset family. Before tracing circuits or writing firmware, confirm the revision marked on the PCB matches 2.2, and keep a backup of the original BIOS chip.
