Re: apple a1286 -- 820-2523-b bios needed

well this motherboard is bit weird . i've cheked all thing i could and all seems nice .
EXcept for MCP PHASE CORE (coil has 0 volts) alltough the pin 19 of the ISL for mcp gives me 1.05 for mcp phase core .. but there is nothing on coil , machine does "turn on" without fully funtional mcp . since phase is not present .

if anyone can help will be nice .

gonna add here both schematic and bdv
