I've got a 2900 which I've been trying to install 2003x64 on, and not having much luck. Either got "no drives found" or "percsas.sys is corrupt" and did not seem to matter if I let nlite do the deed, or modded by hand or even a little bit of both. Oh, joy, just got a new one "syntax error in the .sif file that setup uses...shut down or restart your computer". <sigh> Getting closer, at least and was going to try the Raid Slipstreamer but it only has/does 32bit drivers, IIRC from the thread. Tried everything I've gleaned from search results, and no joy as of yet.
