I have one funky 5500.The machine was origionally a 5200/75 and I put a 5500 board that I recovered form a mac that had probably beenout in the rain for about a year. The board is perfect, no rust, no scratchs. I got at least 5 different Farallon pci ethernet cards from the same source. I have tried a bunch, but the ethernet won't show up in apple talk. I have tried downloading drivers, but the servers were down. I need drivers or something. The card shows up in the system profiler. I need help, please!
