Hi, I'll try it today, though I'm not sure that it will fix lost last dword on read. But at least it should stop corruption on write... After your mail I noticed that there is couple of `unsettable' options in BIOS, and I did not tried switching BIOS from optimal to slow setting yet, so maybe there are more broken optimizations? I'll keep you informed.
