I use EEPC 5.2 and I installed it on WIn 7 Prof SP1. Unfortunately if encrypt drive then I cannot start Windows . After logging to EEPC system restarts and again and again. Obviously without encryption ( only EEPC installed ) working good.. Ok I see that my Dell has RAID technology ( Intel Rapid ...) When I switch to AHCI then works. So question: Will it work with this feature ?
No. As per the release notes RAID is not supported.
If you don't have two drives you don't need it either though.
