Uh... standard PCI is 4 byte wide, 33 MHz - 132 MB/S. This is more than 1 Gb/s. There may also be other traffic on the bus, but you should still be able to get more speed than a 100 Mbps network. If it's worth it obviously depends on the cost and the benefits... some computers might need it more than others. -- Trond Eivind Glomsrød Red Hat, Inc. _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
