I have been out and got a Samsung SATA DVD OEM Drive. I forgot to take of the IDE first to try it. Soon will know in a few hours when I sit down again and try the SATA. Just wants the Cables fitting now. Will clear the CMOS (Again) just incase it still picks up the other SATA drive in its memory.
I have a similar motherboard & now recall it pauses for quite a while at the beginning of bootup - at the initial post screen, but OK once it gets past that. I've tweaked some BIOS settings in the past to no avail, then left it alone.
I never ever considered that IDE drives could be the cause of the problem! That's until I saw your post & went looking. I've 2x IDE DVD-rws installed. Will remove them to see if it makes any difference & post back. G
or any other Forum member familiar with the Asus P5Q SE motherboard. I have found that on boot the Marvel reports Hard Disk not found (which is connected to SATA 1 on Motherboard and DVD Wtr no a SATA DVD Wtr is ok unles Marvel controller is reporting as HDD - unlikely.
I take it when fitting/cabling up a SATA DVD Wtr and a SATA HDD the the Sata goes on the First Sata conector on this board then the DVD Wtr on the second like the older config use to be for ATA IDE drives.
