Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am trying to enable dma on /dev/hdd.
I found a few threads that said that I will need to add a line to /etc/modules.conf file. Will the line be: options hdd dma=1 ?
I have no idea how to do this. I figured out how to change it from 16 bit to 32 bit though. hdd is a partition on my hard drive right? It wouldn't be a hard drive problem would it? It is an 80 gb two year old drive.
O.K. hdd is not a partition of the hard drive. hdd is the dvd player. The line I needed to add to /etc/modules.conf is:
options hdc-cd dma=1
I figured out how to do this on my own.
But, when I did it my -Tt score went from 13.36MB/sec to 1.67MB/sec to INPUT/OUTPUT error. Then I tried xine again and it still plays(poorly) If I have got the thing so scrambled that it can't test itself how does it still play. I tried removing the line. xine-check says I have dma problems again. What is this input output error. How do I correct this?
Sorry if that is a bit vague. If you google 'HDIO_set_dma failed' you will see this is a not uncommon gotcha. Maybe there is some boot parameter to fix things??? Otherwise you probably have to recompile the kernel. Where did you get your kernel in the first place?
Later: the VIA82CXXX support is also available as a module, so you might be able to modprobe it: 'modprobe via82cxxx', if you think that might be the problem.
