Yes, that was the problem. I managed to find the manual and discovered it had been jumpered as non-PnP (not by me; I inherited this machine a couple of years back to use as a PPP dialer and had an ISA NIC in it until now). > Also the PCI latency is IMHO too high. > Try setting it at around 40. That will affect the throughput of the NIC, or its reliability? Or both? I'm not too concerned if its just throughput, because (horror!) it has only ancient 16450 UARTs (one byte FIFO) on the multi-I/O card which are driving a 56k modem. I think its a very positive reflection on FreeBSD that despite this antique UART, which is being driven at 115200 baud, the PPP connection works very reliably and with pretty good throughput (there are the odd silo overflow log messages, but they don't seem to be a real problem). In fact this ancient 486 with 16Mb RAM is doing a fine job as a web cache, print and mail server. -- Dr Graham Wheeler E-mail: gram@cequrux.com Director, Research and Development WWW: http://www.cequrux.com CEQURUX Technologies Phone: +27(21)423-6065 Firewalls/VPN Specialists Fax: +27(21)424-3656 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
