@fognerval It really depends on what this means “after several changes to have the tftpd and http boot I am stuck” What was changed from the fog default install.
Also please answer the other questions I asked. We need to get the full picture of what you are tying to pxe boot and what might have changed by you from the default fog installation.
Did you touch/change the FOG/FOS kernels or inits? I’m not talking about Ubuntu but the FOG supplied target boot kernels.
