Venue 11 firmware updates...

Has anyone developed a neat method for deploying firmware updates for Venues?

Previously we have used bootable x86 WinPE/CCTK USB keys to prepare our machines for the build process. However, if using EFI then the WinPE/CCTK must be x64, however the Dell update utilities don't run under this environment (e.g. system firmware (mistakenly referred to as BIOS) are 32 bit utilities and WinPE x64 does not contain the required WoW components. 

We have looked at a temp 'legacy' boot i.e. allow x86 WinPE, but the DUP for Panel and SSD firmwares don't run in this environment....

We have hundreds of these units to deploy and they all require 'BIOS', Panel and SSD firmware updates...

Any suggestions welcome!

Thanks
