Remember that a 64-bit PCI slot is required. : :Hi! : :Aren't the Netgear's autosensing? Had some GA620T (the CAT5 variant) there :for testing, and it autosensed 32/64 bit. :(Ok, had some probs in an Alpha with an IRQ above 16) All 64-bit adapters do autosensing for 32/64-bit slots. Then what is your next question ? The important point is that -- For standard 1500 MTU, if you want to have GigE adapters able to reach their maximum throughput, you must to use a 64-bit PCI slot. It does not mean that a 64-bit PCI slot is required for a adapter. It is required for the maximum throughput :-) -Jin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
