Acronis True Image 11 - No restore to onboard Intel ICH9R-RAID5-System

Dear all,

after a crash of the a.m. system, I know tried for several days to restore the system volume.

System: WinXP last revision
True Image: Acronis® True Image Home® Version 11.0 (Build 8.105)
Controller: Intel ICH9R onboard
Drives: 3x WD7500AAKS00RBA0 (750 GB)
Partiotions: 1. 50 GB System, 1337 GB data

The files are restored but as True Image does not recognize the three drives being a RAID system but single drives, the system will not boot. It hangs everytime after BIOS installations and - I think - just when accessing MBR or something like this.
I guess the MBR was changed by the RAID-System when creating the RAID volume.

Any one with a good idea ?

Thanks a lot.
A.B.
