=================
Kenneth,
What Ken was trying to point out in his mail was not so much how to fix 
your problem as how to make it a permanent fix.  If you never reboot, 
just issuing the command hdparm will get it going, as you found out and 
it will last, until your next reboot.  So if you want it to have DMA 
turned on with each boot, then go to the file and add /dev/hdd to that 
line.  

#
 # force dma to "on" for the following ide devices
 #
 DEVICES_FORCE_IDE_DMA_ON="/dev/hdd"
