DMA settings are already enabled on all my IDE disks except for the DVD
[root]# dmesg | grep -i dvd
hdc: ATAPI 40X DVD-ROM drive, 512kB Cache
[root at gnu root]# hdparm -d 1 /dev/hdc
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
hum, dma cannot be set ! is this a feature ?
