P60 Firmware Family - Revision History:Have you managed to downgrade to that old bios? I thought it was not possible to downgrade from a 2.X bios to 1.X.
WARNING: AMT must be enabled before downgrading from any 2.XX BIOS version to any 1.XX BIOS version. This requirement is due to a ME Firmware mechanism incompatibility between these different major BIOS versions. After a successful BIOS downgrade AMT can be disabled.
