# hdparm -d1 /dev/sr0
/dev/sr0:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Inappropriate ioctl for device
HDIO_GET_DMA failed: Inappropriate ioctl for device
So, could someone please advise how to enable DMA
for the cd/dvd/rw drive?
It would sure help my aging laptop to play high quality
1080p HD movies.
PS: Keep in mind that ide-scsi emulation is used on all
modern linux kernels since way back ????
