I am running amd64 on some dell poweredge 1950 boxes. They're xeon processors, but have chosen amd64 because they have 8gig of ram each. Here are the relevant details on the interface.... bce0: <Broadcom NetXtreme II BCM5708 1000Base-T (B1), v0.9.5> mem 0xf4000000-0xf5ffffff irq 16 at device 0.0 on pci9 bce0: ASIC ID 0x57081010; Revision (B1); PCI-X 64-bit 133MHz miibus0: <MII bus> on bce0 brgphy0: <BCM5708C 10/100/1000baseTX PHY> on miibus0 brgphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseTX, 1000baseTX-FDX, auto I could make a machine available remotely to someone if it would help. Any other advice on how I can help move this forward would be greatly appreciated! thanks, scott
