Archive for MSI board 7024, presumably the MS-7024 desktop motherboard, with 1.4 in the name likely indicating revision or document version; size is 842 KB in RAR format. MSI desktop boards of this numbering use MS-70xx codes. A schematic of this kind helps follow VRM phases, standby rails, clock generator and power-on signals when diagnosing a no-post fault. Check that the PCB revision printed near the board number matches 1.4 before relying on component values.
