Slackware 10.1 -- DMA not enabled

How would I go about enabling DMA for slackware?

Currently it takes 5 minutes to boot due to the lack of DMA --
I'm not quite sure what information you will need....

Any help?

Use hdparm to enable DMA

#hdparm -tT /dev/hdXX (XX=your disk number and partition)
will give info on your data transfer speed

#hdparm -d1 /dev/hdXX
will enable DMA

If you get an error (HDIO_SET_DMA Failed : Operation not permitted), you probably don't have support for DMA enabled in the kernel - recompile.

Slackware is built on the KISS (keep it simple stupid) principle, mean the default boot up script are pretty minimal. If you want DMA to be set on at boot, you will have to create your own script
