Sam Leffler noticed this on his nx6125 last December and I also found the same problem on my nx6125 in early February. It looks like there's a race condition in the BIOS code. >Any Ideas?

I would also be interested in any real solutions. --=20 Peter Jeremy --FLPM4o+7JoHGki3m Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (FreeBSD) iD8DBQFE6EIJ/opHv/APuIcRAhnaAJ0ZUFTaqh7o8OMLz30IKoeHikAonACdGs5Z t83musWbrlhCSqRXVpfiBQQ= =8BzA -----END PGP SIGNATURE----- --FLPM4o+7JoHGki3m--
