Hello kmccarn,
I reinstall the SME 7RC1 with single hardisk on a Activy 300 (Celeron 366, 256MB, 1x 10GB HDD) and it works fine.
I used the GUI-version to create a backup, but there should be no matter if GUI or commando used.
The only thing that is different: another version of afio, but that should not be the problem. I could send you the compiled rpm.
Best regards,
Daniel
