Let me quote from http://www.heise.de/ct/english/05/08/172/ "In the case of two thirds of all the PCs inspected the security functions were not frozen; and this group included not only devices cobbled together but also current branded PCs by Dell, HP and Apple. Of all BIOSs, the most popular one, Award BIOS, was unaware of ATA Security." If you think that Award does handle things correctly, then maybe we must get down to BIOS versions. Andries
