ok, that sounds logical, but i just did a dmesg and i get this pertaining to 
the CD drive:

that looks like its already using DMA for the CD.  am i correct assuming this?

thanks!

So it looks like you may be using DMA for your CD.  I also found this 
link to a chart for the different DMA modes.


http://bugclub.org/beginners/miscellaneous/udma.html

Also, if I type /usr/sbin/eeprom at the prompt:

ata-dma-enabled=1
atapi-cd-dma-enabled=1

Do you also get =1

Execute

eeprom atapi-cd-dma-enabled=1

from the command line.

Your optical drive is using PIO instead of DMA to do I/O.
