nVIDIA MCP55 southbridge. However, the Super I/O chip on the S2927 is a SMSC SCH5017 and not the Winbond W83627HF found on the S2912. The S2915 uses the nVIDIA NFP3600 + NPF3050 as the southbridge and the SMSC 5307 Super I/O controller. Would Yinghai's patch support either of these two boards? Thanks, Arvind
