I just did it and it worked perfect! I did also have to disconnect the second HDD for the Micron controller to boot the first HDD. I left the second one hooked up at first and it kept trying to boot from it. Disconnected it and Windows XP booted right up. Installed the drivers, shut down, reconnected both HDDs back to where they were, booted up and now have a new SATA contoller in Device Manager.
I ran the HDTach test and got the burst speed about 5mb/s faster than before, so I'm happy as a clam!
I do notice now though that the DMA for both drives is not shown in Device Manager anymore. I also have a SATA DVD burner and now Device Manager does not show the DMA for that one either. I can open up Nero Info Tools and see the DMA for both HDDs there and it's now Ultra DMA 6, where before it was DMA 5. The Info Tools does not show the DMA for that SATA DVD though. Dunno how I'm going to be able to see that now.
