That is OK. I will try it.
In fact, I have posted this problem in 5 forums (4 in Chinese and LinuxQuestions in English).
I also discuss it in IRC, but no one can solve it. The FreeBSD is sleeping in my harddisk for about 2 month. I think if I can't solve it before Debian-sarge being releaseed (September?), the place which FreeBSD will change owner to Debian, I think... ... And I don't want this happen.

Thanks you all, and hope that the maillist will help me

The networkcard is the only hardware which is not decide by myself.
When I buy the service of ADSL, they provide me this card, and it seems work well in my WinXP and Mandrake Linux. I also using it after I change ADSL to LAN. This card is about $5 in market. How about "D-Link DFE-550TX"? Can it work in BSD? It is $21 in the market. If I am going to buy a new card, $21 is the maximum price I can accept. The first Hardware needed to update is my CPU I think. because my Celeron900 is too slow.

I also play games in WinXP. NBA Live! 2004.........So I need a VedioCard which is no so bed

Bulldust. Realtek cards aren't bad. I have one in all my systems, and I've never had even the slightest problem with any of them. Celeron 900 isn't too bad either, I have dual P3-800 and it runs quite sweetly.


Does this problem happen when you boot the install CD?

What did you mean? I boot my computer with the CD1 of FreeBSD, and install the system from CD-ROM. But by the step of configuring networks, the network interface list have no 8139. What can I do for it?
