Embedded iPXE menu to choose which network adapter to boot from (autodetects up to 10 adapters)

Go into your git checkout folder of ipxe.

Save the below file as nic-menu.ipxe.

Build iPXE like this:

cd src && make EMBED=../nic-menu.ipxe && cd ..

Requirements: current iPXE as of 2013-08-01 (for proper behavior of autoboot with a network device specified, netX feature, PCI vendor/device ID display and inc command)
