Hi, I've tried the driver included in 2.4.6-ac5. If it's compiled into the kernel I receive a "No array found" message. If I built it as a module, ataraid.o is ok, but insmod pdcraid.o writes out: prcraid.o: init_module: No such device I've debugged the kernel and found out that problem is that it doesn't recognise the disks, the ideinfo structure says that the disks have 0 heads. Any idea? Bye, krtom
