[ltp] hdparm & DVD CD-RW

[brianweber4 at attbi.com]

I have a combo DVD/CD-RW.

In Redhat 9.0 file:/dev I can see: /dev/dvd--->/dev/cdrom--->/dev/scd0

How can I set up hdparm to emable DMA transfers? I see no other link 
after /dev/scdo. Do I need to make a link to /dev/hdX? is so how? if not, then 
what else should I do?

Thanks.
