Take a look at http://www.codemonkey.org.uk/post-halloween-2.5.txt Excerpt: CD Recording. ~~~~~~~~~~~~ - Jens Axboe added the ability to use DMA for writing CDs on ATAPI devices. Writing CDs should be much faster than it was in 2.4, and also less prone to buffer underruns and the like. - Updated cdrecord in rpm and tar.gz can be found at *.kernel.org/pub/linux/kernel/people/axboe/tools/ - With the above tools, you also no longer need ide-scsi in order to use an IDE CD writer. - Ripping audio tracks off of CDs now also uses DMA and should be notably faster. You can also find an updated cdda2wav at the same location. - Send good/bad reports of audio extraction with cdda2wav and burning with the modified cdrecord to Jens Axboe - Currently only 'open by device name' works in cdrecord. cdrecord -dev=/dev/hdX -inq - More info at http://lwn.net/Articles/13538/ & http://lwn.net/Articles/13160/ Rudo.
