Since high-speed CD-RW/DVD-RW recorders (32x - 52x) are commodity now IMO it makes sense to review hw.ata.atapi_dma default of 0, since apparently PIO mode can't support necessary sustained data transfer rates anymore. For example I had had problems burning RWs on 16-24x with several drives in PIO mode, which gone when I've switched to DMA. I easily imagine newbies who make a conclusion that "FreeBSD sucks" after installing FreeBSD and finding that they can't burn CDs, while other operating system do it without any problems. -Maxim
