Sorry, you're right! I don't know what mistake I made before that thought lspci does not exist! But it does not help! Compiling linux is difficult and I was looking for an easier solution. I tried to edit image of ZeroShell and replace drivers, but it does not work and there is no easier solution than compiling it again!
Thanks for your help.

It's so nice! ZeroShell does not have lspci command! It is removed from OS! But it would not help me if ZeroShell had lspci, because OS can not detect driver to show it as the result of this command. Should I install ClearOS on the system to detect the driver?!
Isn't there any way to copy all the drivers of network from ClearOS to ZeroShell and ZeroShell detects the right one and use it?

The OS can not recognize the Interface. It's a command base OS on server and when I want to see the interfaces, it says there is no interface!
Yes, I have posted on so different forum, includes that, but I have no got any answer yet.
Is there any global way to find drivers on an OS and copy them to another?

The whole results of running "uname -a":
Linux zeroshell.example.com 2.6.25.20 #1 SMP Thu May 14 23:12:00 CEST 2009 i686 GenuineIntel unknown GNU/Linux

Dear All
I searched a lot about my problem, but I have not found any solution about it. Would you please tell me what can I do or where should I ask this question?
I'm trying to install ZeroShell on a ClearBox(model: CAR-3000) but Zeroshell can not identify the network interface and says "No Network Interface".
I found no drivers for ClearBox network interface, so tried to install them, by copying /lib/modules files from ClearOS to Zeroshell, it did not work either.
Is there anyone who knows what should I do?
