Hi Thilo, Are you saying that your ataraid driver supports RAID-1?! It may not have been clear, because I only mention the actual RAID level in the subject line. I do indeed have 4 IDE ports, but due to the inability of IDE to have more than one outstanding I/O per bus, I prefer only to use one device per bus. Therefore, I would like to use the Promise channels to run software raid from.
