On, the other hand problem with 4Kn is deeper as it doesn't seem to even be any implicit agreement of how such disks should be handled for booting. Nor does it seem any impmentation on either bootloader or BIOS side. > Chris Murphy > _______________________________________________ > Grub-devel mailing list > Grub-devel@gnu.org > https://lists.gnu.org/mailman/listinfo/grub-devel --------------enigF0615E281E8421B68BDD853D Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iF4EAREKAAYFAlFHi0QACgkQNak7dOguQgl5RgD+Lff7QyZHbcyEwT7n8bPA6jAU 95iLX4IenyEX7p14oEgBAJ/rRDKTcauzz1kPtQtxiWhaozrFvDOTn+lhzDSrcyWs =UN0S -----END PGP SIGNATURE----- --------------enigF0615E281E8421B68BDD853D--
