Asus P6T Deluxe V2 MB Intel i920 4GB ICH10R RAID 0+1 running about a year.
After power failure, on boot receive this message after Windows splash screen. "The Logon User Interface DLL I:\WINDOWS\system32\awgina.dll failed to load." The normal way to recover appears to be, to start in Safe Mode and edit the Registry to correctly poiint to MSgina.dll However, Safe Mode does not complete the boot, after messages "Windows is starting up, Loading your personal settings, logging off, saving your setting, Loading your personal settings, and continues looping these messages.
Another way is to use the Install repair from the Original install disk. Using this disk, and pressing F6 to load the RAID drivers, when it asks for the RAID driver disk, it fails to recognize the disk. After creating a new RAID driver disk from the MB disk and trying again, same result. Downloaded latest version from ASUS site and made another F6 disk, same results. Another way is to use the recovery console, but install crashes with a suggestion to use CHKDSK /F before the Recovery console option is available. The Intel Matrix Storage Manager (option ROM v126.96.36.1998) shows all disks normal. But, Status = Verify
Apparently the RAID array is not properly seen by Windows on Boot. Do not have a clue why the install disk does not recognize the 'F6' driver disk.
