1 hard drive on ide1 and 1 CompactFlash on ide1

Problem Description:

My CampactFlash is my primary hard drive and don't support DMA. My hard drive
support DMA.

When I boot I have a timeout :

dmesg :

If I boot with append option "ide=nodma", I have no error but I can't activate
DMA on the hard drive :

hdparm -d1 /dev/hdd

doesn't work.
