Do you remember those D-Link ethernet cards I got? Well they came, but Linux 2.4.x doesn't like them. DeLi spits out a bunch of unresolved symbol errors when I try to modprobe the module (which is 8139too) and DSL doesn't even recognize its existence. I have yet to get the module for BasicLinux so I can try it on Nettlewark, but I imagine it won't be much better.
And even worse, I think the 486's power supply is shot. When I turn it on I hear a low frequency clicking noise, and it gets to a higher freq if I switch it to 110.
