Hi, I'm really happy to hear about this! Please keep on working on this. Your work is awesome... It was just a tiny step and i would have thrown away my promise sx4 and bought an 3ware raid5. but, i keep on waiting! i'm really looking forward till that day we have raid5 commited to ata. (at that day i will curse my dual-athlon for taking to long compiling current :) ) Thanks Soeren!
