Hmmm... if I realised that I wouldn't have been so hung up about getting a board with RAID support in amd/64! (Although I do like the Asus A8V Deluxes now I've got one.) I assumed on-board RAID was a step up from geom but maybe not. I guess performance in geom wouldn't be any slower either if it's all software-based. Ashley
