Boardview for the MSI A68HI AC desktop motherboard, model code MS-7969, revision 1.0. MSI uses the MS-79xx style numbers for its own desktop boards, and the code is usually printed on the PCB near the slots. The .cad layout shows part positions and net connections, which helps when probing CPU VRM, memory and standby rails, checking a shorted capacitor or finding the SPI BIOS chip. It opens in common boardview software such as OpenBoardView or FlexBV. Verify the revision on the board first.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardviews. Enginerys does not host this file.
