I've never had problems with mpt, so I haven't wasted a thought about checking compatiblity before I bought 3 LSI20320IE... Unfortunately I'm now in production with my choice and I worry about trashing my DAT72 because I can't keep it streaming. I checked the same setup in a different (WinXP) Guest-VM and it resulted in a 5,5MB/s stream= =2E If I can help, please let me know. I could setup either a VM-Guest with the 20320IE passed through and an DAT attached, or a real box with the same components. Both with extra serial remote-console. > > hw.mpt.X.role means target/initiatiator/both/none. > I guess it's starting with 0, so my 20320IE has role "none". Is that just a cosmetic bug?
