I have held back doing this because I didn't have the time to mess=20 about with it. If I were to configure a new kernel without legacy ATA=20 drivers, how would I know what my devices will be seen as in advance, so th= at=20 I can change my /etc/fstab before I reboot? =2D-=20 Regards, Mick --nextPart3621753.PVYWddzpPR 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 (GNU/Linux) iEYEABECAAYFAkiDUS4ACgkQ5Fp0QerLYPfNvQCfR36SV6d9NC9hSj0zyh68VMTS 51kAnAwJpoItuEgkEaXD+4kJEnCOVefS =qx4M -----END PGP SIGNATURE----- --nextPart3621753.PVYWddzpPR--
