Hello All,

I am trying to work on getting a PCI-E card working and came across an error that I am wondering if I need to worry about.  Below shows that the VGA ROM is loading, but not the ROM from the PCI-E card (at the bottom).  Both of these cards are in slots and not onboard.  The PCI-E card is an Ethernet card.  As the device is getting a bus and resources seemingly just fine, I would think that the ROM would have been found.  My question is … do all add-on cards need to load an expansion ROM or can they run just fine without it?  The error in question is “Incorrect Expansion ROM Header Signature ffff”.

FYI on devices:

00:01.0 is the PCI-PCI bridge

02:06.0 is the VGA card on the PCI-PCI bridge

00:02.0 is the PCI-E bridge

04:00.0 is the ethernet card on the PCI-E bridge
