This isn't quite true.. Due to the implementation of console over firewire, it will work before it is probed... This is due to the fact that console over firewire examines the memory directly (becaue firewire supports reading/writing memory w/o the host cpu's intervention), and doesn't need anything special to be initalized... Recently, loader was improved to support dcons, and support hand off of the buffer from loader to kernel... I haven't tried this new and improved loader, but it's suppose to work... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
