[mythtv] hdparm question

[Ryan A. Carris]

I got MythTV working well, just need some fine tuning of the rest of the 
system now.  Hopefully, this will be my last question for a while.

I've turned on 32 Bit Access (wow, what a difference) and DMA using 
hdparm.  It really helps. I have a 80GB WD Special Edition 7200RPM 8MB 
cache drive.  My video goes from jerky to smooth.

Question, and I think this will help a lot of people:  How do I get 
32bit access and DMA set at boot?

I was guessing by changing /etc/fstab, but after reading 
http://linux.oreillynet.com/pub/a/linux/2000/06/29/hdparm.html (a good 
read,thanks to the person who suggested it here) it indicates that I 
need to add a script to my /etc/rc.d/*.

Could someone please explain how to do this.

Thanks,
