Archive for the Compal motherboard LA-C341P, revision R10 (likely 1.0), sized at 287 KB. Its size matches a companion entry for the same board marked as boardview, so it most likely contains layout data for locating components and test points. Boardview files are opened with programs like OpenBoardView or FlexBV and are used to trace nets while chasing shorts or absent voltages. Compal is the ODM behind LA- numbers; confirm the board number and revision silkscreened on the PCB before use.
