# 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 ???? -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
