It definitely sounds like DCM is a 0. If you can't get DCM & LDO to save as a 1, it's not going to work, maybe a bad board? I would try to load the R23 generic then a profile through Hyperterminal. Or if you have access to a UIT, you could use the net Preset menu and save to flash. I'm not sure if you can access that menu through IMS or not, that R24 software is quite new.
