This As someone who has been playing with PIIs and fxp nics over the last couple of days, I have found a few things that *might* help. On the ASUS MBs (both LX and BX) that I was setting up I found that the Intel card on both NT and FreeBSD would work very poorly depending on which PCI slot it was in. If the card was in the first slot (the one next to the AGP), on NT I would see all sorts of dropped packets and ethernet errors. It really manifested itself on NT with PCAnywhere losing its connection every 2 min... On FreeBSD, very poor network performance even when on a straight cross over cable to another box. I think it has something to do with lack of busmastering on all PCI slots. It might be a long shot for you, but try putting the card in the middle of the BUS, and give it a decent IRQ (e.g. 5 or 10) thats not shared with other devices. On the LX chipset, the last 2 PCI slots share IRQs which I imagine would hinder performance. Also, with 256MB of RAM, make sure you disable the speculative reads in the BIOS.... As for kernel configs, build a customer kernel at least... Get rid of what you dont need and yes, upgrade to stable. I have a few boxes that regularly push > 5Mb on a 5min average (yes, just bits), but they perform quite well... ---Mike ********************************************************************** Mike Tancsa, Network Admin * mike@sentex.net Sentex Communications Corp, * http://www.sentex.net/mike Cambridge, Ontario * 01.519.651.3400 Canada * To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
