[vox-tech] DMA disabled on device LITE-ON - DVDRW SHM-165H6S

[Jimbo]

Greetings:
I received an error msg when bringing k3b  'DMA disabled on device 
LITE-ON - DVDRW SHM-165H6S.
It further went to say : 'With most modern CD/DVD devices enabling DMA 
highly increases read/write performance. If you experience very low 
writing speeds this is probably the cause.  Solution: Enable DMA 
temporarily as root with 'hdparm -d 1 /dev/hda'

I did as suggested w/o a hitch.  First time seeing msg since updating k3b.

Is there a way to permanently enable dma easily for this uber  newbie 
can understand?  Googling brings up unending questions hence this letter.

Thanx,

Jimbo
