That means that the system will not crash anytime you'll use DMA above the 16 MB limit. Not enough for you ? :-) Bounce buffers are the difference between crashing with more that 16 MB is you have a DMA-ized adapter and running perfectly well with it and more than 16 MB. I'm not concerned anymore by them since I switched to EISA but great thanks to the FreeBSD team for the great [and speedy] work ! -- Ollivier ROBERT Ollivier.Robert@keltia.frmug.fr.net A FreeBSD & PERL addict...
