Quoting Freakshow

I actually had to register here to just to ****ing let off my steam. WOW at you ****ing idiot users saying BIOS and Controllers 'MUST' be the same. I've even moved a RAID 0 array from a VIA8237 controller to a Promise controller on another board, and it immediately booted up to Windows..

Don't speak without experience. Yes it very well can work. It is not a guarantee. And it won't damage your data, it just won't recognize the drives if there is a problem.

I know this post is old, sad to see people have had to read all these 'seem to have been there, done that' answers. To people like the above poster, they actually thought they got some knowledgeable information.... Let's hope you guys didn't help him with anything else, or he probably has fried CPU's and corrupted data on hard drives.

Welcome to Icrontic! I hope you have found more here that interests you and stick around to see what the members here do know. If you are keen you just may be surprised!

Now back to where I was. The original post is 5 years old and the hardware was much different back then. It was much more likely that an array would not transfer from a MB based controller than likely to transfer. Also, the user had not backed up their data on a RAID-0 array, which is just outright stupid. If you notice, the general consensus was that the original poster do 2 things. First and most importantly, back up their data whether or not they proceed to move the array from one board to another. Two, they were advised that while it was possible it was recommended not to do it. I have been lucky as well but several months down the road started getting random errors that only got worse with time. I ended up rebuilding the array from scratch and transferred my data back to the new array. With very few exceptions most posters replying have a substantial amount of experience on the subject. At no time was the original poster given bad or dangerous advice that would have cost them their data. As to the "been there done that" replies, experience is still king when it come to advice! If an alcoholic wanted to get clean, would they ask the bartender or drunk in the alley how to do it? NO! They would ask those who had done it successfully! As to your success with switching from a VIA 8237 controller to a Promise controller (cir. 2005) was more luck than success. Even a fool standing on top of the tallest point of a relatively flat area in a thunder storm will get lucky on occasion!
