Greetings all: I have a several PCs with MSI K8T Master2-FAR7 MS-9617 (v1.X) Workstation Boards with two AMD Opteron processors at 64 bits, to which I have installed Fedora Core 5 for 64 bits. This motherboard has a Broadcom BCM5705 Gigabit Ethernet controller for 10/100/1000 Mbps. I also have a 3COM Gigabit Switch in order to make them work as a mini-cluster. When I connect them all I can not get them to comunicate through the Ethernet port found in the above mentioned Motherboard. However, if I install a generic 10/100 Mbps Ethernet card I am able to make them work as a cluster, but at 100 Mbps. My problem is that I DO NEED to get them work at 1000 Mbps, and I am wondering if any of you has any idea of why I can not use the Broadcom Ethernet port. I am afraid that Fedora Core 5 does not have the driver for this motherboard. Any ideas?
