[Dvdrtools-users] Enabling DMA on sparc Solaris 2.6?

[Duplantier, Guy (Mission Systems)]

dvdrtools/cdrecord_prodvd users:

I have a trial version of cdrecord-prodvd-2.01b29-sparc-sun-solaris2.6 running 
on a sparc Ultra 10 workstation with Solaris 2.6.  I'm trying to burn a DVD on 
my Pioneer DVR-107 DVD-Burner.  I get an error that suggests enabling DMA.

How do I enable DMA on an Ultra 10 sparc Solaris 2.6 box?  I can't find 
anything on the Web including Sun's site that describes this.

Thanks,

-Guy Duplantier

Here is the error that I get:
