Could it be a mismatching PCI_ID? You could try the config with MS, where AFAIK, it does SATA300 mode. You could try skimming forums on ocworkbench.com for info, as this is kindof an asian homeforum, with JCM360 being designed by .tw Jmicron. Whatever, it may or may not be worth too much trouble. I'm thinking JCM360 may have an unclear future, since AFAIK the later ULi chipsets have native SATA 300 support, and nVidia bought ULi, perhaps to produce entry level chipsets (according to press). I was very interested in that same board, due to very good test results and features, but skipped it for the very JCM360 driver issue. Being a dirt cheap board, you could spend on a separate selected SATA interface (to keep for the next board). The mobo certainly has enough PCIx slots for that. What's you overall experience with the board, WRT stability/performance? -- Kind regards, Mogens Valentin
