WDS Legacy BIOS and UEFI boot

[jae1378]

I now have devices with UEFI coming in. Some have Legacy/UEFI support others are UEFI only. I have upgraded my WDS/MDT server to 2012 R2 and MDT 2013. I can boot Legacy devices into WDS/MDT with no problems. I have DHCP option 67 set to boot/x86/wdsnbp.com. When i try to boot a UEFI device (Dell Latitude 3330) it gets to the succeed to download nbp file, then it goes right back to the laptops boot menu. When I change option 67 to boot/x64/wdsmgfw.efi the 3330 boots into wds and i can choose my 64bit MDT boot image. So my question is, can I have my cake and eat it too? Is it possible to have both legacy BIOS devices and UEFI (32 and 64bit) devices boot into wds. If so, which boot file do i need to set or what do I need to do to get them to work. I feel like Im missing something simple. Thanks for your help.

We haven't done any special config. We don't add the option to dhcp. We just use ip helper as ms recommend. The few uefi devices boot fine.

I found exactly the same thing using DHCP options. Switching to using ip helper on the switches resolved the EFI/BIOS problem, though I haven't been able to get 32-bit EFI to work. Suspect this may be down to inadequate support on the devices I've been testing, however. Edited December 13, 2013 by AngryTechnician
