I had exactly the same problem when I tried to install 2.0.5R on my
machine (GATEWAY2K, 486DX/2 50MHz, 16MB, AHA1542B and SMC Elite16). A
few days ago, I asked this problem to questions@freebsd.org but no one
has answered to my quesion so far. The only work around, at least for
me, was "not to probe ed0" :-) As long as you set correct port addr,
irq, iomem, you can proceed to install FreeBSD.
