Try disconnecting the drives and see if it moves past that error, one of the drives may be hanging the controller. If it does move past it probably is not a controller issue and you can try reinserting the drives.
Hi all,  I have a misbehaving R510 that is complaining about "Foreign configuration(s) found on adapter."  Normally I can clear it either importing with F or going to config with C.  However, this machine won't accept the F or the C (despite offering it) and I can't break out early with any of the BIOS options or Ctrl-R.  Any advice on how to escape this?  The keyboard works (I can get into the enet stuff with Ctrl-S), but otherwise it's stuck.    Thanks Jack
