how can I turn DMA on, during installation or after it. I need it to run some multimedia files. It works just fine when I boot it from a cd with dsl dma comand, but once I start it from hdd it shows dma turn off.
thanx for help
___ "OšO" [~]If you can boot to dsl after hd install, then this next thing should work: /sbin/hdparm -c3 -d1 -m16 -ki /dev/hda
You need to be root to do that.can also append it to your LiLo config then run LiLo as Root, or append it to Grub config file.
Robhdparm -c3 -d1 /dev/hda
Is an Amazing improved towards my disk performance!
I checked the speed with doing
Code Sample
dd if=/dev/hda of=/tmp/test.dd bs=1M count=100
dd gave me , 50Mbyte/s transfer rate
Without DMA enabled -> 5.4Mbyte/s , Speed x10More hdparm settings and a great primer on the subject here, I already had dma going but there is so much more you can do to squeeze a very nice bit of speed out of that hard drive check it out here O'Reily hdparm Tutorial
