Grub and pxe boot

[Patrick Begou]

Hi all,

I look for a workaround for a network installation of some laptops, may 
be using grub.

- the laptop is behind a dock station (U2723QE from DELL) which must do 
a pass through of my laptop nic mac address.

- The PXE boot provides the right mac address to the dhcp server and 
downloads the grub.cfg file, the  kernel...etc

- then booting the kernel launch a new dhcp request but this time with 
the U2723QE mac address. And this fails.

I would like to provide a fixed IP address via the grub file to try to 
fix the problem. But I'm unable to reach a documentation about the full 
syntax of the allowed commands like ip=??? (I use ip=dhcp) or other 
useful commands.

I saw also somebody speaking about a "keeppxe" command which may help 
but no idea about using it.

Thanks for your help or some documentation I could read.
