Booting on pre-RiscPC machines is not yet implemented.

No installer has been written yet. Incompatable changes may be made.

Built using the sources and patches below, though to patch 18.


I have a copy (signature) of grub (2) 1.91 (signature) avaiable for download, to which the patches below may be applied.
