No idea why that matters. My DVD drive is SATA too. I > need to play with that more later on. See if it was that or something > else that I missed.

My notebook works like that too. Hard disk works fine when everything is set to AHCI, but then the system won't boot from CD. So I enabled the IDE driver and the IDE driver for CD-ROMs. My take on this is that Dell had a vast stock of cheap-skate CD-ROM hardware and used them up. The engineering logic would have been "it doesn't matter that we use the slow interface for that device, it's still faster than we can get the data off the media." -- alan dot mckinnon at gmail dot com
