Boardview covering the ASUS H81-PLUS desktop motherboard at revision 1.01, compressed to roughly 105 KB. This board uses the Intel H81 chipset, and a separate 1.02 revision file also exists, so reading the revision mark on the PCB matters before diagnosis. In OpenBoardView, FlexBV or similar tools the layout shows every component location and net link, making it easier to trace a short on the CPU rail, locate missing standby voltage or find the clock generator and BIOS chip.
