DMA on hard drive is turned off

[Dswissmiss]

Hi guys,
When I boot into Linux, I get a DMA on the hard drive is turned off error. How do I turn this on? Would there be any problems if I did so?

Thanx

A couple of ways...

hdparm -d1 /dev/hda

(must be root) The above will enable it on drive a (the first IDE drive in your system). Try that and make sure it doesn't spit out any errors. If it works and you don't have any problems, you can tell it to enable DMA at boot in your boot loader.

If you're using lilo, you would put this under the section for your default kernel in /etc/lilo.conf...

append="ide0=dma"

(with the quotes just like that)

Then save the file and run...

lilo

And you'll be DMA enabled by default when you reboot. This is assuming that you're using the first IDE drive in your machine (primary master). If not, replace the a and the 0 with whatever drive you're using. Primary slave would be b/1, secondary master would be c/2, secondary slave would be d/3. If using grub or some other boot loader follow their nuances for appending kernel options at boot time.
