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?

Thanks - Joe
