Hello, Is there a way to run a PCI rom before the PCI bus scan runs???
Yes, we have to do this on any later geode. The LX port should give you a hint on how it's done.
Sorry, but how are you going to run a ROM before you know where it is located? I can see a way to run an image of a PCI ROM before PCI bus scan if the image resides in main system flash, but otherwise...

Ok, let me be more specific. I am pretty sure the pci rom for the 82562ET nic runs and powers on the onboard ethernet device. The nic does not have an eeprom. All the device settings are kept in the pci rom on the bios. After the rom runs it enables it, sets up PHY registers, sets up it PCI config registers, and requests use of the PCI bridge. That is why I need it to run before the PCI bus scan.
Make sense?
