My pall has now added a SATA disk on the mother board and installed XP (trying something else than windows 7) on it with the correct driver. Now we can se the Adaptec card in the device manger but we se no disks SAS disks.
We solved it. We had done som misses in the Adaptec config. However, after fixing the Adaptec config we formatted the discs in XP (Because we could se the discs in XP but not in Windows 7 install) which changed the diskd into basic disks (not dynamic) and then we could get the Windows 7 install program to work.
