UEFI BIOS Task sequence for Windows 8

Hello

I am looking for automation script  / task sequence that can be used via MDT 2012 for mass deployment of Windows 8 with UEFI BIOS configuration.

Is there any scripts, detailed steps available .

I am looking for these for the hardware models Dell E6230, E5430 and Optiplex 3010.

Appreciate any one early response as this is quite urgent for my customer POC.

Thanks

Suresh Raghupathy
