DMA settings won't save
I'm running Slackware 9.0, and I have:
hdparm -X66 -c3 -d1 /dev/hda
in my /etc/rc.d/rc.local
When linux loads, it works reads that DMA is on, but when I log in and type:
hdparm -Tt /dev/hda
I get really crappy speed, and when I type
DMA is turned off, but when i turn it back on again, then it works fine.
Anybody know why I would have to type 'hdparm -X66 -c3 -d1 /dev/hda' again when linux starts? or if there is a better way to enable DMA and hard drives?
