After dealing with a lot of things I finally was able to provision the Lenovo ThinkPad Tablet 2
The PXE representative script have to have this two lines:
REMCOPY16=%DTMDIR%\landesk\vboot\bcd_ia32.dat, %LDMS_CLIENT_DIR%\bcd_ia32, TOREMOTE
REMCOPY17=%DTMDIR%\landesk\vboot\bootia32.efi, %LDMS_CLIENT_DIR%\bootia32.0, TOREMOTE
Make sure that in the PXE PC have this path
C:\Program Files (x86)\LANDesk\PXE\System\images\IA32 EFI\UNDI\bstrap
I had to use the ThinkPad USB 2.0 Ethernet Adapter (it does not work with another Ethernet Adapter)
Add the Tablet using the MAC address of the Ethernet Adapter to the "Bare Metal Server", schedule your template and drag and drop the Tablet created then start the task. Turn On your tablet (I use a USB Hub) press F12 and boot from network (Select IP4)
I hope it helps
