Schematic in PDF form, packed as RAR, for an ECS B40IAX board identified as MB40IA revision RB1. ECS boards are often sold under other brands, so the board code is the reliable identifier. The circuit diagram lets you trace power sequencing, follow signals between chips and find the values of components around a failed rail. Open it in any PDF reader and search net names. Check the board code and revision printed on your PCB before relying on part numbers or values.
