How else would you start pxeboot.n12?

It is this Windows Boot Manager that needs to know where it can find a valid BCD file (not another NBP). This is what I need DHCP option 252 for - to tell "bootmgr.exe" what file to pull off the TFTP server and use as the BCD.

Yes, so you have: pxelinux.0 -> pxechain.com -> pxeboot.n12 -> bootmgr.exe.
