Maybe I'm misremembering, but was sure I did it. Of course, I no longer have that hardware available. The only hardware I do have will only manage 850Mb/s (933MHz PIII, 64-bit/66MHz PCI, Netgear GA620T CAT-5 GbE card, PC133 SDRAM - none of it recent hardware, but that's the best a beleaguered telecomms company can do...). --jim
