BackDrivers Package for the Mesa Pro
25 Jan 2023
The drivers and apps needed for a custom OS build are contained in our OS Patch. You may find the following support article to be helpful: Loading Custom Windows OS image on Mesa. The instructions for Windows 10 on the Mesa 3 are similar to what would be needed for Windows 11 on the Mesa Pro.
Firmware and OS patch installers are available for the Mesa Pro. The OS patch installer can behave as a drivers package installer using a few additional command line arguments as follows.
-passive Install without user input through the user interface.
-osinstall OS patch acts like a Drivers Package instead of a Patch. Referring to the following registry values:
[HKEY_LOCAL_MACHINE\SOFTWARE\Juniper Systems]
"BuildJDate"="23000" ; Displays in the Device Settings App as Original OS Version.
"PatchJDate"="23001" ; Displays in the Device Settings App as the Patch OS Version.
When the -osinstall argument is used, it sets the OS version value HKEY_LOCAL_MACHINE\SOFTWARE\Juniper Systems\BuildJDate instead of HKEY_LOCAL_MACHINE\SOFTWARE\Juniper Systems\PatchJDate, to indicate that this is an Original OS Version number, and not a Patch OS Version number.
The -osinstall argument sets the following registry key with the value noted below:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity]
“Enabled”=dword:00000001
The reason this is not installed by the patch is to allow the end user the choice to disable Hypervisor Enforced Code Integrity.
The -osinstall argument installs both cellular drivers, regardless of what cellular module is installed. Note: Without the -osinstall argument, the cellular drivers only update if a cell module is found. Using this argument will force the cellular driver for both cell modules to update, regardless of the cell module found.
The OS Patch (drivers package installer) does not contain the graphics drivers. Use driver from Intel® Graphics – Windows* DCH Drivers.
The installer is not intended to be extracted for manually obtaining raw driver files. If you need individual raw driver files for your Mesa Pro OS image development, please contact support@junipersys.com with details of your specific needs.
