I have two questions about this: 1.) How much benefit is bus mastering for UNIX (assumming the OS supports it) 2.) Does either BSDI or 386bsd support bus mastering? One other question, what exactly do the Adaptec cards do that make them more expensive than the Future Domain cards? ------------------------------------------------------------------------------- Jeff Hollingsworth Work: (608) 262-6617 Internet: hollings@cs.wisc.edu FAX: (608) 262-9777 Home: hollings@warthog.madison.wi.us Home: (608) 256-4839 X.400: <pn=Jeff.Hollingsworth;ou=cs;o=uw-madison;prmd=xnren;c=US>
