RedBoot, from what i read, seems to be > i386 specific. The Yamon i've patched "COULD" be made to do it. I haven't looked at how initrd support is really done in other arches. But I think the kernel copies the initrd image from its original location to a new location, so I don't see why the original location couldn't be in flash. You could just pass the physical address to the kernel, and have the kernel load it from flash to ram. Pete
