Cross Post: PXE Boot into OME ?

Hi, 

 I know I can build and maintain an ISO to update systems but was wondering if anyone has setup and environment to PXE boot a Linux kernel and register the device with OME for firmware updates?

This is a provisioning, spare pool VLAN where machines DHCP into for firmware updates, inventory etc..

 Anything  you have to share would be appreciated.
