(specially when dell bios is=20 compressed and image itself contains flashing program...) What I now found is this table of SMM commands: https://lkml.org/lkml/2008/12/18/44 So it looks like SMM data are in some NBSVC.MDM binary. Do you=20 know something more about it? =2D-=20 Pali Roh=C3=A1r pali.rohar@gmail.com --nextPart280083472.T4ZWy06Ems Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEABECAAYFAlN4cQAACgkQi/DJPQPkQ1JkxACcDmYy7Nf0ZX42f+S0vuSiNeU/ 7/kAoL/X2r7xw6XELqYru/wq1ztlDPOL =Q49W -----END PGP SIGNATURE----- --nextPart280083472.T4ZWy06Ems-- --===============6762703188879992539== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ lm-sensors mailing list lm-sensors@lm-sensors.org http://lists.lm-sensors.org/mailman/listinfo/lm-sensors --===============6762703188879992539==--
