PXE boot Panasonic CF-19 problems

I'm having problems booting a group of Panasonic CF-19s into WINPE using a pxe boot server. The problem comes when WINPE is loading up I get the "cannot create MBR.bin" error. I believe I have the correct drivers for the NIC but they are in multiple files besides .inf which is what the Ghost Boot Wizard looks for. What I need is a known fix for this or a guide on EXACTLY how to insert the correct NIC drivers into the WINPE image so they load properly and I stop getting the aforementioned error. Does anyone have any insight on this? I think I have all the pieces but can't get it to work. Any help is much appreciated.
