And now you see one of the many reasons GRUB has not yet been ported to run under LinuxBIOS.

A bzImage had a real mode component that must be run below 1MB. Currently I place the ramdisk at 8MB, and the converter and the real mode code could be placed on top of that. I do something like this for the Itanium. Still it is less than satisfactory to require that to happen. 0-640K is always known to be there so we should be able to use it. Hopefully some time will open up and I can put out another ELF booting specification.
