[help] how to make blank undionly.kpxe

[biatche]

###1###
After embedding, will i still require this (it's in my embedded script now) on my dhcp server:

dhcp-boot=http://192.168.0.xx/xxxxxx/bootstrap.ipxe

if in the case the chain link in the embedded script is broken, what happens? will the above line serve in dnsmasq serve as backup?

###2###
your link also brought me to notice:

make bin-x86_64-efi/808610de.efirom # 64-bit driver ROM

that got me interested in building UEFI pxe.

Do I just type: " make bin-x86_64-efi/808610de.efirom "
and that it would automatically know it has to build a 64bit efi rom based on filename?

zlib and binutils header files (only needed for EFI builds)
[ebuild R ] sys-devel/binutils-2.21 USE="nls -multislot -multitarget -test -vanilla"
[ebuild R ] sys-libs/zlib-1.2.5-r2

I have an old linux box, which i dont intend to update, will those versions suffice for EFI?
