Read single ITE 8212 RAID1 disk using plain ATA -- possible?

I have a system with a recently-deceased Gigabyte motherboard with an onboard it8212 RAID chipset and two RAID1 arrays configured. I am at my wits end trying to get the machine working again and I am trying to extract my data from the drives on a plain old ATA controller on another machine.

The problem is that the other controller shows the drive to be empty, understandable as the RAID controller no doubt uses a non-standard partition table. I have a few ideas I am pursuing but I don't know if any of them are viable.

Since my arrays are configured for mirroring instead of striping, I would think each of them contains a complete, valid NTFS filesystem and that it's just a matter of determining the correct partition location/size and creating a partition table with that information. Does anyone know of a utility to find the RAID partition's location on the drive?

Another possibility would be to find a PCI RAID controller with the same chipset and hook the drives up to it. Although, I am unsure if configuring the BIOS in the card would destroy any partitions that exist on the drives now.

If neither of those pans out, the other option would be to find the same motherboard, but that will be tough since I'm fairly certain it has been discontinued/supplanted.

Any help would be appreciated.

Thank you.
