Any option that is a dependency must first be enabled in order for the previously undisplayed option to appear!!

Also here, we did not have any ipxe.0 file. It just worked as any other client. The tricky part was reconfiguring the uefi bios to boot from the lan using pxe. Once we found how it was needed by those particular clients they just worked!! > By the way, if pxe-boot is not depending on uefi or legacy bios ... > why > does the uefi client need the ipxe.0 file instead of pxelinux.0? Careful. I said that booting from the lan using pxe resulted in a client running in legacy mode, not uefi mode. To explain what I mean let's take a straight forward case of installing a 64 bit Debian Jessie or Stretch to an empty hard drive. If the installer is started from a medium that the uefi bios regards as non-uefi it will go ahead and install the system which will not run in uefi mode. See http://www.rodsbooks.com/linux-uefi/ where he says, "You should verify an EFI-mode boot by dropping to a Linux shell and typing ls /sys/firmware/efi. If you see a list of files and directories, you've booted in EFI mode..." For us this was a non-issue since we were only interested in getting these clients to boot with pxe, not to run in uefi mode particularly.
