FOG 1.2 is having issues with any MBR.
My E520s and E530s (maybe even 531s, haven't tested those yet) all seem to fail when init.xz is loading.
Here's what happens:
Computer starts PXE boot. I get the FOG boot menu and fog will read the MAC of the NIC and tell me the host name. If I let the menu time out, then the computer boots normally.
If I try to register the host, upload an image, or even download an image (Win 7 or 8.1) fog will load the BzImage file and then the init.xz file.
Once the init.xz file is loaded on the problematic Lenovo machines, all the lights on the NIC go dar and the computer sits for about 90 seconds, tells me a message that it is trying to reopen network connections for a few more minutes, and then fails with the message that network medium not found.
As soon as FOG fails and goes to reboot, the NIC lights come...
