How to rebuild a two drive raid 1 array on Linux?

I need to rebuild a two drive (160x2) raid 1 (mirror) array. It was an Intel raid from a 7 year old Dell computer (Windows). Both drives are assumed to be functioning. The raid was created with an on-board motherboard raid program. It's been quite a while since I had to rebuild a raid, and the last time it was a raid 5 that had been created on Slackware. Where do I get started? I'm putting them in my personal machine and I'm guessing that Linux is going to be the tool to get this done.
