I installed a new DVD-ROM drive today, an ASUS E616P1 (Pioneer 121) and it works fine in DMA. In fact, it works great, I was ripping at 12.1x. But now my NEC drive is stuck in PIO. Device manager shows it as running in DMA if available, but the current mode is PIO. Is this due to my new drive, or is it just being lame? Is there a fix?
EDIT-The 2500A is set up as master, and the ASUS as slave, if that is any help.
