There is a 3Com/USR 56K external modem running off the onboard serial for my incoming faxes and the printers are running off USB and parallel (onboard, both) * Tried a AGP version of a ATI card (Rage128) but the TX underruns happened alot more often until I swapped it out with the PCI version, this is leading me to believe there's perhaps a bus contention issue here. Anyways, as before, if anyone has any ideas, please speak up. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
