Chainloading from ipxe to multiple pxeboot roms

[NiKiZe]

Yes, iPXE by defaults supports booting pxe binaries, this is the default if no other way of booting the file is detected, this can be seen by doing imgfetch http://file followed by imgstat and it will show you detected type.

(just to be clear here, PXE NBPs is a legacy only thing, and it is not possible to support from EFI mode)

You can boot most things directly from ipxe, linux kernels, NBPs etc, and there is even wimboot for booting WinPE so most of the time there is no need to load other loaders, other then possible during migration to ipxe when you don't have time to migrate everything at once.
