you know where you have to go for the redhat-docu ;-)
do you know where you have to go for eg. PLD-Linux ?
sure, the first step should be the homepage.

As I understand it the preferred method for turning on cd/cdr/rw dma is 
not with 'hdparm' but by editing '/etc/modules.conf' and adding the
following line.

options ide-cd dma=1

But if I am mistaken, someone will correct me no doubt.

I'm still having failures erasing/recording *new* 2x CDRW disks, 
but for 4x and upwards, four sessions of burns / erasures 
with X-CD-Roast, and Gnome Toaster have gone OK!

Thanks,

not sure, perhaps here:
/usr/src/linux-2.4.*/Documentation/
because it is not here
/usr/share/doc/initscripts-*/sysconfig.txt

finding the needed information is a process who should start before you 
have a problem ;-)
