I have used it on my A2000. I didn't like it, and removed it after a week. I found with the Budda installed, it took almost a full 3 minutes to boot into 3.1, once i removed it, it takes less than a minute. I only was using it for a CD-rom drive. My Mobo was rev 6.
With no documentation to be found anywhere, I didn't even try to fix or diagnose to problem. If you want, I have my for sale.
