Revision 1.04 boardview for the ASRock B250M Pro4 motherboard, packed as a 588 KB ZIP file. It belongs to the Intel B250 chipset generation of micro-ATX desktop boards. Repair work benefits from the ability to click a component and see its connected nets, find the SPI flash, check pull-ups and probe power rails without a full schematic. Use a viewer like OpenBoardView or FlexBV after extracting, and confirm that the silkscreened revision on your board is 1.04 so the layout lines up.
