problems building vbox rom

[iucounu9]

Hi,

I'm trying to rebuild a VirtualBox PXE ROM to include ELF, bzImage and a few other protocols as I am getting an exec format error. So I uncommented these in config/general.h and then ran the build as follows:

make CONFIG=vbox bin/intel--virtio-net--pcnet32.isarom

It builds fine but the protocols do not show up in the banner when loading, just the previous ones. Of course I removed the old ROM I'd built with the default protocols, and installed the new one with the extra protocols enabled with vboxmanage (as described).

Is there something I am missing in the build process?

Thanks for any help,

Cam
