An earlier Z97-K boardview, version 1.05, distributed as a 175 KB RAR archive. It covers the original revision of the board, so placement and nets may differ from the later 2.0x layouts. Load it in a boardview program to search parts by designator, highlight a net across the board and find measurement points when hunting a shorted rail or a missing voltage. Check that the revision printed near the PCIe slots or the board edge reads 1.05 before relying on the placement it shows.
