Grub2 is a nice boot loader working on many platforms (x86, sparc, ppc) and now you can try it on your Pegasos/Efika. If you want know more about this program visit

I tested it on Pegasos 1, Pegasos 2 and Efika and it works just fine on all of them (Yes on P1 too, but some adjustments in OF are required in case of this machine)

There is still some problems, but it should be functional enough for normal use. I am not grub developer then I am not sure how correct my changes are, but I send patches to grub mailing list already.
Big ThX for 'nyu' from #grub for some background informations and help.
And finaly please in case of any problems do not ask grub developers for help as they are not resp for my changes just poke me here or on irc (FreeNode, #castor-cvs)
