I've been trying to play DVD's and such in FC5 but it's laggy as all hell. DMA is turned off on the device and I'm pretty sure that's why it lags so much.
I tried running:
/sbin/hdparm -d 1 /dev/hdc
but unning hdparm only returns:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
[root@localhost Kobnar]# gedit /etc/rc.d/rc.local
Note: I did hdc because "df" shows me that my DVD device is /dev/hdc/ (probibly has somthing to do with the fact that my computer is a Thinkpad and the CD/DVD drive is connected by an internal hot-swap USB port)
Does anyone know how I could turn DMA on?
Any help would be appreciated.
