Artifacts in the bias are not necessarily a problem if they are consistent and don't take up too much of your dynamic range.

Ivan, I done bit of reading on subject and I think that the lines are artifacts form interlaced CCD chip. But then it is a bad software driver, I had couple of cameras with interlaced chip and none had this problem. By selecting good Bias frames I can get good Darks.
