Unfortunately, this driver is not=20 available to be loaded as a module either. the GENERIC kernel comes with t= he=20 needed driver (called bt). You don't have to compile a new kernel, but you= =20 are going to have to replace the kernel on the disks with one containing th= e=20 needed driver (like GENERIC). Either way, the recovery procedure involves= =20 booting off a CD and replacing the on disk kernel. =2D- Thanks, Josh Paetzel PGP: 8A48 EF36 5E9F 4EDA 5A8C 11B4 26F9 01F1 27AF AECB --nextPart2652044.uH5mUclLDF Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEABECAAYFAkikRlkACgkQJvkB8SevrssY/ACfWkrR0MHAIoWhNMVGhU5Np+fl EvUAnjeci1JK8rzyEdE0g93miqPBlmJw =RMpW -----END PGP SIGNATURE----- --nextPart2652044.uH5mUclLDF--
