[CentOS] Centos 6.5 problems with UEFI PXE and GRUB

Greetings,
Im having issues booting UEFI PXE Centos 6.5 using Grub.  Ive followed the configuration specifications in the documentation and yet my install always seems to hang past the grub menu at
[Linux, EFI ...]
Ive added ksdevice=bootif and APPENDIP 2 to ensure the proper nic is selected however this does not prevent the hang.  Im not making it to the repo as evidenced in apache logs either.
