WDS, iPXE, DHCP and SecureBoot

[NiKiZe]

SecureBoot is only relevant in the case where the client boots in EFI mode, as such you can look at http://ipxe.org/howto/chainloading#uefi where a simple example is made about how the dhcp arch option is used to determine if a pcbios compatible version of ipxe should be sent or a efi compatible one.

so what you would probably like to do is to always boot ipxes undionly.kpxe in legacy/pcbios mode, and in efi mode chain into the wds.efi

Even if you can detect EFI or not as a base with the above mentioned arch option, there is no option or detection AFAIK in dhcp for if secure boot is enabled or not.

And mandatory question: you are aware of wimboot which makes it possible to boot winpe via http download? which is probably many times faster then the default WDS TFTP method.
