Archive for the ECS 661FX SF2 motherboard, revision 1.0, a 754 KB RAR file. The board belongs to ECS's SiS 661FX family, and the name does not say whether the package holds a schematic, a boardview or a BIOS dump. Extract it and review the contents first. Useful for tracing power rails, finding the flash chip for reprogramming and checking voltage regulator sections on old socket boards. A separate rev 2.2 package exists for this model, so read the revision on the PCB carefully before relying on these files.
