You basically have 2 choices on setting up PXE. You can remove your current option 67 and reconfigure DHCP options to point at the TPMfOSD server. Found this doc here - http://www-01.ibm.com/support/docview.wss?uid=swg27027022
While DHCP options have their benefit, I personally prefer to setup IPHelpers. You probably already have IP Helpers forwarding bootp packets to your DHCP server. You can simply add another address so that bootp packets go to both the DHCP and TPMfOSD server. The pxe proxy feature of TPMfOSD will send the necessary boot information to the client while the dhcp server supplies the IP address.
Back to the software deployment options. Having the install packages in both tools is not ideal, so I keep them in TEM and then setup ‘breadcrumbs’ to be deployed within a TPMfOSD task. By breadcrumb I simply mean a file or registry key with the product name/version. You then have some policy driven tasks in TEM that install the software whenever the file or registry key exists. Very simple to do and prevents you from having to keep packages in 2 locations.
