Before buying a lot of these tablets (Venue 11 Pro 7130), I have to ensure they can be deployed from MS Configmgr (2012). So far I have no luck getting our test model to PXE boot.
Following the instructions documented by Dell here: 
I have a USB to Ethernet Lenovo dongle based on the AX88772B chipset...which is supported according to the documentation. However, trying to PXE boot, the screen hangs on the message:
checking media presence...
start pxe over ipv4
It then moves to ipv6, and then boots on the hard drive. BIOS version is A14.
Any help would be appreciated!
