[Ham-Computers] Drive DMA Mode versus PIO?

[Philip, KO6BB]

Hi All,

Today I loaded some Guitar recording software (RIFFWORKS by Line 6) on my 
computer to try out.  It's basically a complete "Software recording studio" 
and operates in conjuction with my Guitar "Pedalboard" which is connected by 
a USB cable.  Before the software loaded it ran a full system scan to 
determine if the system was properly configured to run it (it doesn't make 
any system changes on it's own).

It detected only one problem, then proceeded to allow me to install the 
software.  The failure reads as follows.
"FAILED      Drive DMA Mode (   0): PIO detected on SONY CD-ROM CDU5212", 
this is my "secondary" CD drive.

QUESTION:  If I recall correctly, I can change this in the bios setup 
routine when the computer starts up.  HOWEVER, will there be any NEGATIVE 
aspects to changing this drive to DMA?  And what DMA mode do I want to set 
up for?

Here is the COMPLETE printout of the report that was generated in case 
somebody needs more information to make a valid suggestions.
