I'd highly appreciate if you could find some time to fix the mpt 53C1030
negotiation.
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.

I guess it's starting with 0, so my 20320IE has role "none". Is that
just a cosmetic bug?

Thanks,
