Problem to use netinstall with PXE-boot option.

HI.
I’ve try to reinstall ROS soft on my x86 router. I have Intel adapter with PXE option.
On the router screen I’ve see that PC gets IP address, but fail to get tftp paramiters.
therefore I do not see anything in ''Router/Drivers" window.

How I can fix that?
Is there any goof FAQ about PXE-boot and netinstall?

Hello

I would also like to know more about the PXE booting of the ROS. Also, say you have a router (ROS) in between the router you would like to PXE boot,

[TFTP/PXE Boot server] -->[ROS router] -->[remote ROS router]

what should you do? Would you be able to dhcp relay the pxe boot server and tftp server? or should you just specify those options on the router between your PXE/TFTP server and the remote router?
