HOWTO Light and Zero Touch Deployments of OS 12

Note: Options for how to deploy IGEL OS in either a light touch or zero touch manner.

OS Creator – Unattended

UMS PXE

  • How to Deploy IGEL OS 12 with PXE
  • More scalable than USB
  • Zero touch after device is PXE booted
  • Requires internet access
  • Medium-high difficulty to setup
  • Lots of moving parts. (DHCP, tftp server, web server, UMS json)

Microsoft Deployment Toolkit or MDT

  • More scalable than USB - requires device to pxe boot
  • Can re-use existing WDS/MDT infrastructure
  • Fewer moving parts (WDS, MDT, shared folder)
  • Low/Medium difficulty to setup
  • Not as robust as SCCM/MECM
  • Not yet a KB article or supported method

SCCM with NO IGEL Plugin - Option 1

  • You control the how and where
  • The image file does not need to be in the boot media, you control where you run it from
  • You keep your existing boot media, you only add files to it, if you want or need to
  • If you use something like 1E Nomad or Adaptiva today, you can use it for deployment going forward
  • How many packages you create is your choice

SCCM with NO IGEL Plugin - Option 2

  • Download the OS12 Base System Deployment Tool for SCCM
  • Extract all the utilities and the OS image from it and put them in a folder on your network
  • Inject dd.exe from the folder into your existing boot media - Optional
  • Create deployment tool packages
  • Create your own task sequences
  • Test the task sequences and deploy
  • Not officially supported by IGEL but works incredibly well

Automatic Device Registration

  • So, you deployed the OS, now what?

IGEL OSCW Enhanced - Under the Hood

OSCW cannot register with UMS through ICG and so you can't do the normal OCSW procedure (register, apply profile, send conversion command).

Here is a method to use the unattended OSC .iso

Summary of steps:

  • Install OSCW
  • Rename the osc-12.5.0.iso to osc.iso (Make sure this is the unattended version of the ISO you created earlier)
  • Copy the osc.iso into the C:\OSC folder
  • Rename grub.cfg to grub.cfg.old
  • Rename osc.cfg to grub.cfg
  • Restart the device

The device will boot using the GRUB boot loader which will trigger the IGEL installation from the ISO.
