I have an IDE DVD drive (/dev/hdc) and I would like to turn on DMA to
speed up playback of movies in ogle.
In SuSE 8.0, I am able to use:
hdparm -d1 -X34 /dev/hdc
to turn on DMA and it makes a huge difference in playback frame rates.
When I use this command (as root) in Red Hat 8.0, I get an error...
/dev/hdc:
Setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
I verified that the device was owned by root and rw for root. Does
anyone know why this doesn't work?
Best Regards,
Keith
