+## How to use a board which uses PXE ?
+All boards which uses PXE, could be used with LAVA via grub.
+But you need to add a configuration in your DHCP server for that board.
+This configuration need tell to the PXE to get GRUB for the dispatcher TFTP.

+```
+  	host upsquare {
+		hardware ethernet 00:07:32:54:41:bb;
+		filename "/boot/grub/x86_64-efi/core.efi";
+		next-server 192.168.66.1;
