RAID is now used as an umbrella term for computer data storage schemes that can divide and replicate data among multiple physical disk drives. The physical disks are said to be in a RAID array, which is accessed by the operating system as one single disk. The different schemes or architectures are named by the word RAID followed by a number (e.g., RAID 0, RAID 1). Each scheme provides a different balance between two key goals: increase data reliability and increase input/output performance.
Ok now that that has been said, let's see about helping OP.
If you have everything hooked back up to the original mainboard and you didn't hose it by connecting it to the intel raid, the raid array should reconnect itself.
If you erased the mbr from it, the potential damage caused by trying to rebuild it on the intel board may be too great and the data while not gone, recoverable only with professional solutions (expensive) but try to rebuild the mbr (fixmbr).
Assuming you can read the data, you will need to back it off onto a non raid drive.
Once the data has been retrieved, break the raid on the amd system, then move your drives over.
Create a new raid on the intel system, make your volumes and partitions as you see fit and put your data back on it.
Remember, moving a raid from controller to controller will almost never work. Moving across controllers on AMD platforms while possible does carry a risk, same as moving on Intel systems. Moving from a raid platform to a different one altogether is a recipe for disaster.
