Yeah, ("software"/"hardware"/"disabled") has been the other dropdown list i= n=20 my BIOS (i remember now;) however, it's been 'disabled' as I touched my hos= t=20 first, and playing around didn't help *yet". although here, the BIOS=20 reference book just didn't talk about this area either. I'll try once again, thx all ;) Regards, Christian Parpart. =2D-=20 Netiquette: http://www.ietf.org/rfc/rfc1855.txt 19:59:46 up 54 days, 9:06, 0 users, load average: 0.66, 0.61, 0.61 --nextPart1953702.zMjJWiU1r0 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQBCiN/0Ppa2GmDVhK0RAsdMAJ9thCxym2YXMDwrnBIkFaKI/q+zpwCeOG/1 Q4qe8a2ebYlMwdFPXtG1bd4= =JI/+ -----END PGP SIGNATURE----- --nextPart1953702.zMjJWiU1r0--
