CUSTOMER NOTES:
This Intel Management Engine Firmware (ME FW) SoftPaq contains utilities and the
appropriate ME FW image files (.bin) to update the Intel ME FW to version
11.12.93.2323 on Z4 G4 Workstations. Also included in this SoftPaq are utilities
to report status and other information from the ME FW.

*****
SPECIAL NOTE: Z4 G4 Workstations support either Intel Xeon CPUs OR Intel Core
CPUs, not both. If manually flashing the ME FW in a Linux or EFI environment it
is CRITICAL to use the flash utilities and the Intel Management Engine Firmware
(ME FW) image designated for your system. If your system is equipped with an
Intel Xeon CPU, you must use the utilities and ME FW image designated for Intel
Xeon platforms. Likewise, if your system is equipped with an Intel Core CPU,
you must use the utilities and ME FW image designated for Intel Core platforms.

Xeon CPU -> 11.12.93.2323.Xeon.bin
Core CPU -> 11.12.93.2323.Core.bin

In some cases, the same flash utility will be used for both Intel Xeon CPUs and
Intel Core CPUs. It will be clearly documented if different flash utilities are
required.

*****

This SoftPaq does NOT include a system BIOS. It is highly recommended to update
your system to the latest BIOS. The latest BIOS 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 Linux environment or an EFI environment.

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) Updating the Intel ME FW in Linux requires root privileges.

3) Linux tools were validated with kernel version 4.15 in Ubuntu 18.04. It is
highly recommended to use kernel version 4.15. However, other kernel versions
may work. EFI tools are also provided for additional update options.

INSTALLATION INSTRUCTIONS:
-----Automated update procedure-----

1. From a terminal, navigate to the directory containing the Update.sh script.
By default, this is the root directory where the SoftPaq was extracted.

2. Execute the following command:

sudo bash ./Update.sh

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

-----Manual update procedure-----

1. From a terminal, navigate to the directory containing the ME FW update
utility:

/ME-Flash/LINUX64/

2. Give the FWUpdLcl tool execution privileges by executing the following
command:

Sudo chmod u+x ./FWUpdLcl

3. Execute the following command. You must use the correct Intel ME FW image
(.bin) for your system. Verify your Intel CPU before proceeding.

***You must use the correct Intel ME FW image (.bin) for your system. Verify
your Intel CPU before proceeding.***

Xeon CPU:

Sudo ./FWUpdLcl -f ../11.12.93.2323.Xeon.bin

Core CPU:

Sudo ./FWUpdLcl -f ../11.12.93.2323.Core.bin

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