This usually indicates a transceiver selection problem, perhaps forcing the transceiver selection to a non-existing type which results in a non-autonegotiated 10Mbps connection. > however, if i disable in-kernel cardbus support, and compile pcmcia-cs so > that i can get the old 3c575_cb driver, the card functions quite > respectably on the 100baseT switch (transfers at ~50Mbit/s with some > bursts much higher). The driver and 3c575 card should work at full line rate. If it doesn't, there is a probelm somewhere. -- Donald Becker [email protected] Scyld Computing Corporation http://www.scyld.com 410 Severn Ave. Suite 210 Scyld Beowulf cluster system Annapolis MD 21403 410-990-9993 _______________________________________________ vortex mailing list [email protected] http://www.scyld.com/mailman/listinfo/vortex
