Unfortunitly I am pretty poor, so purchasing new equipment right now is not a good idea. Now I was wonder if any devs who has some free time wouldn't mind adding OpenBSD support for ATI IPX. I found some linux drivers that could get ported across at http://www.kernel.org/pub/linux/kernel/people/bart/atiixp_ide/. I am willing to test out anything that somebody could come up with. My computers took 1 1/2 days to compile needed ports up to and including qt3, its pathetic :(
Thank you, Richard
