Lenovo E530 and FOG 1.2 Issues

Hello, 

My school is migrating from Windows 7 to Windows 8.1 - I have upgraded my FOG server to 1.2 and am having a strange issue when I attempt to upload an image from a Lenovo E530.

The computer will boot into PXE and will start to load the FOG kernel; however, after it processes init.xz, FOG attempts to reopen network devices, but the network port remains dark and the FOG upload fails because it can not access the network. Rinse and repeat. 

I never had this issue with older versions of FOG and this laptop model, and it doesn't seem to be related to the WIN 8.1 install, so I was hoping someone may have a solution for this issue.

Thanks!
