I was poking around the Tyan web site and noticed their partial list of drives that do not support dma. I was wondering how much error checking FreeBSD's ide dma driver does. In other words, if I enable it with my current drives, is it likely to hose my filesystems? Does it query the drives and only dma to those that support it? My current drives are an NEC DSE1700A 1.7GB pio4 capable drive and an WDC AC2850F 850MB pio3 capable drive. My motherboard is a Tyan Tomcat IV D with 32MB EDO and currently a single pentium 200 MMX running a uniprocessor 2/8/98 current. Hopefully tomorrow I will be able to fire it up with two cpu's. :) Also does ide dma work in smp mode?
