Description
This package creates files that contain an image of the System BIOS (ROM) for the supported notebook models with a 68IRR family ROM. This package is used to flash the System ROM on a supported notebook.
This package includes several methods for updating the BIOS version as follows:
– Use the HPQFlash Utility to update the BIOS directly in a Microsoft Windows Operating System environment.
– Use System Software Manager (SSM) to update the system BIOS on PCs in a network.
– NOTE: To determine the ROM family and ROM date, press F10 on the notebook during startup to run the Setup Utility, and then view File/System Information.
Changements:
– Fixes an issue where the system appears to enter recovery mode after Intel Trusted Execution Technology (TXT) is disabled in the F10 BIOS menu.
– Provides improved security of UEFI code and variables. HP strongly recommends promptly transitioning to this updated BIOS version which supersedes all previous releases. NOTE: Due to security changes, after this BIOS update is installed, previous versions cannot be reinstalled.
