dma?

[kryptus3]

i just installed knoppix 3.2 on my compaq 1200 laptop. At startup it says that the dma on my hard drive is turned off. In laymen's terms, how do i turn it on?

To turn it on, open up the file /etc/hdparm.conf using a text editor as root. The simple way to do this is open the program Konsole and enter the following commands:

su
kwrite /etc/hdparm.conf

Scroll down to the bottom of the file and you should see these lines:

#/dev/hda {
# mult_sect_io = 16
# write_cache = off
# dma = on
#}

Uncomment them by removing the #'s so that it looks like:

/dev/hda {
mult_sect_io = 16
write_cache = off
dma = on
}

Save your changes and the next time you reboot, dma should be on.
