The modprobe.conf on the computer in question hasn't been altered manually, and looks like modprobe.conf on other Fedora 7 computers I have. > I have the below in mine for example.

I have 5 workstations, all purchased within three months of each other. All are the same model and the same specs were used to purchase them. The 3 older ones have 82566DM as their network (according to lspci). The 2 newest ones have 82566DC-2 according to lspci. DM works great, DC-2 not at all. And I just can't figure out what to try next. Mike
