OK, but *probably* this is an indicator that you need to either replace the cable (think you said you've tried that) or replace the motherboard. If the cable is known-good and the other components are known-good, and it won't run with DMA on supported hardware, something is seriously wrong with this particular board and odds are too high that it will die horribly later. (Not to mention that you'll be hammering your CPU just to get lousy throughput out of it.) As you said in the other post, you've already spent hours of your life you won't get back - do you want to sign up for some more hours further down the road? -- Clifton (suddenly questioning why I'm spending hours on mailing lists today) -- Clifton Royston -- cliftonr@iandicomputing.com / cliftonr@lava.net President - I and I Computing * http://www.iandicomputing.com/ Custom programming, network design, systems and network consulting services
