PREREQUISITES:
PREREQUISITES:
1. Intel Management Engine must be enabled in BIOS. The option to enable ME is
located in the Advanced menu under Remote Management within BIOS setup (F10 BIOS
menu -> Advanced -> Remote Management). Please note, older BIOS versions may
only include a single option to enable the Intel Management Engine Interface
(MEI) device in BIOS. The Intel AMT option must be enabled in order to update
the Intel ME FW when only one enable option is available in BIOS setup. Newer
BIOS versions include separate options to enable Intel ME and Intel AMT
independently. In these cases, Intel ME must be enabled, while Intel AMT may be
enabled or disabled.
2. Intel Management Engine Interface (MEI) drivers are required in order to
update the ME FW in a Windows environment. It is highly recommended to install
the latest ME SW from hp.com. (https://support.hp.com/)
3. You must run the MeInstaller.exe, FWUpdLcl.exe, or FWUpdLcl64.exe with
administrative privileges. If User Account Control (UAC) is enabled you may see
a UAC prompt when using the silent install options (MeInstaller.exe -s).

appropriate ME FW image file (.bin) to update the Intel ME FW to version
11.22.97.2675 on Z6 G4, and Z8 G4 Workstations. Also included in this SoftPaq
are utilities to report status and other information from the ME FW.
