Hi,

I have my linux booted from an external USB hard disk. I had this setup for my laptop.

Now I am trying to use the same (without any fresh install) hard disk and set it up for my PC (not using for my laptop anymore).

I am able to boot and also reinstalled my nvidia drivers. So display is fine. But my network/internet eth0 is not working.

Can someone help me in reinstalling ONLY the network driver so that it can work normally ? I am not sure where to start from also !!!

Also can you tell me what other things [drivers..etc] I should probably be worried about to reinstall to have no problems ?

Which distro and version are you using ?
Did you get error message ?

Printing some output..please let me know if you need more data
the distro is debian 4

OK.. I found the stuff out [needed to compile atl2.ko] and am now able to set it up and start browsing yipeee!!!
BUTTT

I am still doing this manually....look at the script below

---------
insmod /lib/modules/2.6.25/kernel/drivers/net/atl2/atl2.ko
ifconfig eth0 192.168.1.25 netmask 255.255.255.0
route add default gw 192.168.1.100
ifconfig eth0 up
#[also modified /etc/resolv.conf to have the nameservers]
-----------


I need to know , how to insert the .ko into the kernel during startup.

added atl2.ko into /etc/modules , but its not loading. checking with modprobe,
modprobe atl2.ko
it says file not found !!!

I think the IP stuff can be modified in /etc/network/interfaces , but I need the module to be loaded first. Any help ????????
