Thanks for your help so far..
What I have done to get it going (not the way I'd like it...) I have built a RAID 0+1 (Mirroring) array using a smart start Version 5.50 CD (Selected Win200 - the only options were Windows or Novell)..
THen instead of installing Windows I turned the machine off and installed SME 6 with the above command line at the appropriate location in time. The only problem is, in order to get the server to boot into the OS properly, I have to use the emergency boot disk .img.... Can anyone please tell me how to fix this?
