I wonder if others can > confirm that. I clarified this in a second post, sorry. I'd recommend trying a copper card with your converter. I've tested that MB and I don't believe the controller is connected to a 64/133Mhz bus. Its less than have the speed (ie twice the load) as an EM card in the PCI-X slot. You can, of course, connect a part to a pci-x buss at 32bits and 33Mhz. Nevertheless, the bge driver with the mobo is suspect (we've had to hack it a bit to get it to work properly with bridging at all). It doesn't seem to want to come up at a gigabit unless you give it an address. The driver is really junk, IMO. DT __________________________________________________ Do You Yahoo!? Tired of spam?
