The _two_ linuxbios.strip binaries? I only see the one in my build tree. I
was going to try and use mkflashimg but I think I need a DoC bit or two I
haven't figured out yet. :-)

:-) I am an old x86 hacker (real and protected modes), but I haven't actively
used my old knowledge for several years. It's embarassing how much I've
lost. I will do what I can along the way to try and document it as I
(re)learn it (especially the boot process that LinuxBIOS takes).
