+Normal install mode for fai is using pxe, but on a libreboot system,

+
+* Use a live cd to call pxe-kexec, this is described later in this file.
+
+* Use the fai autodiscover iso. This is more automated, so nicer.

+* Use an install method above to setup a gnu/linux disk partition that

+Things I haven't tried:
+
+* There is iPXE, which requires standard bios functions, which can be
+  provided by seabios, which can be a libreboot payload.

+* The bios chip has enough room for an initrd. This could be setup to
+  work like the partition I use to kexec, but it would be faster, and
