Enabling PXE on 82576 NICs

Hi fellows,

I have an Intel Gigabit ET2 Quad Port Server Adapter plugged in an Intel Motherboard Server S1400SP2. When I checked the BIOS configuration, I only see the options to manage PXE for my onboard ports.

Could you please tell me if there is any way to enable PXE for my offboard NIC through the BIOS.

Thanks.
