I agree this shouldn't happen. >Can anybody suggest anything about this problem? It looks like stand-alone PIC code on FreeBSD needs some different incantations to Linux. My understanding is that several of the i386 bootstraps are relocatable so you might like to peruse the code in /usr/src/sys/boot/i386 for ideas. --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --GvXjxJ+pjyke8COw Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkkKAQEACgkQ/opHv/APuIenPACeP23KxKxwHhnUk82BZHgW0JST 8bQAn1a41Ti/4d8q8ZGSvHBJ/a4grW8x =aW3q -----END PGP SIGNATURE----- --GvXjxJ+pjyke8COw--
