hdparm -tT /dev/hda

gives reading of read speeds for hard drive

hdparm -d /dev/hda reads out wether DMA is enabled ot not

hdparm -d1 /dev/hda enables DMA

hdparm -c dev/hda reads out wether 16bit or 32 bit support is enabled

hdparm -c1 /dev/hda enables 32bit support

more or less same principle can be aplied to /dev/hdc or hdd

add those lines to end of /etc/rc.local to make it auto enable on boot

also you may need to add
hd-cd dma=1
to end of /etc/modules.conf
