Trouble PXE booting Thinkpad X1 Carbon 3rd Gen (Type 20BS) to K2000
Hey everyone. I've scoured the web, and come up with nothing. I'm having trouble PXE booting a new Thinkpad X1 Carbon 3rd Gen (Type 20BS) to our K2000. I've downloaded the SCCM driver pack from Lenovo, applied the NIC and storage drivers to a newly built KBE, and still nothing. We are still deploying Windows 7, using WinPE3 boot environment. These Lenovos are the only things giving us problems. New Dell systems still boot without issues.
I am able to boot to the NIC, select my boot environment, and see where it says loading KBE00034.iso............ It runs the ... across the screen for a while, then blinks and jumps back to the screen to select either my boot environment, or the local hard disk. So, I'm guessing I'm still missing a driver, maybe for storage? I've exhausted what I can think of, and don't like having this really pretty paperweight on my desk...
Any ideas or suggestions would be greatly appreciated.
