[SOLVED] No IP address when boot finished

[agent_kith]

the model is this one : http://www.asrock.com/mb/Intel/Q1900TM-ITX/

it has only one Lan

that's the Q1900TM, it's using a Qualcomm NIC. You'd need to update the kernel of your LiveCD to get it to work.

Go here and download the file vmlinuz-4.4.9-rt17-amd64-qualcomm.tar.bz2, you'd need a special archiver program to decompress a tar.bz2 file. I think winrar should do the trick.

Expand the file you've downloaded. You should get the following two files:
config-4.4.9-rt17-amd64-qualcomm
vmlinuz-4.4.9-rt17-amd64-qualcomm

In your USB stick there will be a boot folder. Inside this folder is a file called vmlinuz. Replace this file with the downloaded vmlinuz-4.4.9-rt17-amd64-qualcomm. 

Boot the modified LiveCD and see if the NIC is detected now.
