FYI, it's been in our tree for a while and I think I mentioned it before, but as a reminder, I have the iPXE protocol exported for other efi applications to use (mostly thanks to Geoff Lywood for initial pass back in gPXE days). In conjunction with an elilo patch I submitted to their list and patches to the ESXi5 boot loader, it enables a behavior analogous to using undionly.kkpxe chainloading pxelinux.0 for http transfer of payload. It was a bit more critical for EFI boot mode since EFI ipxe can't directly chain linux kernels.<br>
<br>The way it currently works is passing through the device ipxe itself seemingly booted from but with an additional handled protocol attached. Only tested in 'snponly.efi' style usage.<br><br>Here are the five commits the support spanned:<br>
