Primergy TX150 and new RAID controller

[Cloud]

Hi, I have a Primergy TX150 that was shipped with a FastTrak that didn't support hardware RAID5.

I've recently bouht a new FastTrak (TX4310) that does, I can configure an array to have a RAID5 as the FastTrak BIOS loads without any problem. After that when the OS should start or when I want to install the OS the computer hangs there with this error message:

Check Point: AE.

I've done some research and it showed up that this error message correspond to something like:

clear IN-POST flag.

I don't know how to solve this problem. Can anyone help me? (The BIOS version is the latest available from the Fujitsu-Siemens site)

Thank you very much!
