Tools and versions:
Pfsense 2.0.1 x64
USB Stick Installer
Cd-rom installer (live-CD version)
WD Velociraptors x 2
Long story short:
Raid Off - AHCI selected in BIOS under HDD option - Install works fine
Embedded Raid on and configured to raid 1, RAID selected in BIOS - As soon as the media loads from CD or USB, the system reboots itself and i never reach the initial pfsense selection screen.
I have tried to change various options in bios however this does not resolve the rebooting issue.
I have also tried to google this unique problem to no avail.
Any advice is much appreciated.
