CUSTOMER NOTES:
This Intel Management Engine Firmware (ME FW) SoftPaq contains utilities and the
appropriate ME FW image file (.bin) to update the Intel ME FW to version
12.0.92.2145 on Z2 G4, and Z2 Mini G4 Workstations. Also included in this
SoftPaq are utilities to report status and other information from the ME FW. In
addition to updating the ME FW, this SoftPaq will also update the Power
Management Controller Firmware (PMC FW) to version 300.2.11.1025.

ME FW: 12.0.92.2145
PMC FW: 300.2.11.1025

This SoftPaq does NOT include a system BIOS or Management Engine Software. It
is highly recommended to update your system to the latest BIOS and ME SW. The ME
SW includes Intel Management and Security Status software, Serial-Over-LAN (SOL)
drivers, and Management Engine Interface (MEI) drivers. The latest BIOS and ME
SW is available at https://support.hp.com/

This SoftPaq includes two methods for updating the ME FW. The ME FW can be
updated in a Windows environment or an EFI environment.

PREREQUISITES:
1) System BIOS 01.05.01 or greater must be installed before updating to ME FW
12.0.35.1427 or later.

2) 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.

3) 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/)

4) 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).

INSTALLATION INSTRUCTIONS:
***Update via HP provided utility:***

MeInstaller.exe is a utility provided by HP to help facilitate the ME FW update
process. The MeInstaller.exe utility can run automatically when the SoftPaq is
extracted (press [Y] when prompted during SoftPaq extraction), or at a later
time by executing the MeInstaller.exe utility from a command line terminal such
as Windows PowerShell.

MeInstaller.exe [-s|silent] [-?|h|help] [-r|restart|reboot] [-force]

-s|silent Update the ME firmware without user input
-?|h|help Display help screen
-r|restart|reboot Will restart the computer after update is successful
-force Forces the install over the same version of ME (allowsv)

Example:

C:\SWSETUP\SPxxxxx\MeInstaller.exe

A reboot is required in order for the new ME FW to take effect.

***Manual update via Intel tools:***

FWUpdLcl[64].exe is a utility used to update the Intel ME FW in a 32-bit or
64-bit Windows environment. The ME FW can be updated by executing the following
command in a “Run” dialog box or a command prompt with administrative
privileges.

32 -bit:

"FWUpdLcl.exe -f ..\12.0.92.2145.bin"

64-bit:

"FWUpdLcl64.exe -f ..\12.0.92.2145.bin”

The flash utility (FWUpdlLcl[64].exe) and Intel ME FW image file (.bin) can be
copied to any available volume/folder within the Windows environment.

A reboot is required in order for the new ME FW to take effect.

KNOWN ISSUES:
- In rare circumstances updating to the latest ME FW with BIOS versions prior to
01.05.01 could result in an infinite reboot loop when powering on, resulting in
a system board replacement. It is highly recommended to update to the latest ME
FW and system BIOS.
