1. When the system is powered on "At this point, the LAN controller is in the D0u state" 2. The "Platform LAN Connect component" is actually a command script (probibly a rom written in assembly) runs and sets up the CSR register (I could setup a script in the mainboard directory and run from auto.c). 3. At this point it goes into a DOa state. 3. The "Platform LAN Connect component" hands it over to the bios (coreboot) to setup "Memory, or I/O Base Registers in the PCI Configuration space" 4. nic is setup and ready to go! What do you think?
