FWIW, we've tried both the SMC and Linksys boards with this DEC chip. The SMC boards worked, the Linksys failed. We exchanged the Linksys EtherFast 100/10 for SMC EtherPower 100/10 (+$50) and things were just fine. We used two Linksys EtherFast boards, different batches from the same store and they consistently failed in the same way. The Linksys 10 Mbit/s with RJ-45 and 10Base2 was just fine though. The symptoms of our failure were complete. No traffic in or out at 10Mb/s, tested with link flags in all combinations, complete with power-down reboots between tests, showed no change in behavior. This was, BTW, true for Linux 2.0.27 kernels, too. Curiously the DEC interrupt test that shipped with the DOS based diagnostics, claimed to be unable to find the DEC chip on our (multiple) test systems. We *really* tried to make this work ;-) I was under the impression that a Tulip by any other name, worked just fine. In practical experience, there seems something different about some boards. The SMC boards consistently work for us. The Linksys 10Mb/s only (RJ45, 10Base2 or AUI) boards consistently work for us. Cheers, Jeremyc. Daniel M.
