My apologies in advance for asking such an elementary question. I
called myself searching the Installation Guide and Deployment Guide,
with no success.
The situation is that I bought a Lite-On ATAPI iHAP122 that will not
burn DVDs unless I use hdparm to turn dma off. I bought that drive
because it was a rare beige drive. Until I can find a decent DVD burner
and/or get a Windows machine put together strictly for doing BIOS
updates, running with dma disabled seems to be the best solution.
(hdparm -d0 /dev/hdb )
So, my question is, where should I script the command without having to
become root each time I wat to burn a DVD?

This is how it always fails:
