To: hackers@freebsd.org Date: Wed, 21 May 1997 09:00:12 +0200 (MET DST) X-Mailer: ELM [version 2.4 PL23] Content-Type: text Sender: owner-hackers@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Hi, one thing I have been long wondering about is whether it is possible to add DMA support for IDE devices. I think many controllers now have this capability, maybe some even implement it right... so, are the docs available somewhere to try and implement DMA mode ?
