Shouldn't be impossible if you manually told coreboot where the PCI device lives.

And there is no eeprom, everything comes from the pci rom in the bios. Here is what I think the PCI rom does with the original bios: 1. powers on and enables device 2. sets up PHY registers 3. sets up it PCI config registers 4. and requests use of the PCI bridge If I could figure out how to do #1 the rest would be fairly simple to setup,although I am not exactly sure about PHY registers. Then I wouldn't need the pci rom at all. > Joe, I think Carl-Daniel is asking: where is the image for the PCI ROM > located?

Yes, the pci rom currently lives in the bios. It is a three part rom, Intel boot agent, Intel PXE, and the base code (I think the base code is the only real part I need??).
