Need of iPXE boot in VirtualBox using a ROM with HTTP support

[robinsmidsrod]

Congratulations! The reason for disabling HTTP on the default vbox build is to make sure you get drivers for all the different virtual NICs vbox supports. To do that we had to strip out almost all of the iPXE-specific functionality and only keep core PXE features.

If you can get rid of core PXE-required features on your specific network you can customize the build further. The purpose with the default vbox configuration was to be able to build a ROM that could replace the non-free Intel PXE ROM used by VirtualBox without lacking any core PXE features.
