Customizing FOG iPXE Settings

See Using the FOG Boot Menu for the built-in commands available at the boot prompt without any customization — this page covers adding your own custom entries and background on top of that.

The entries below are static, but they do not have to be: iPXE Menu Variables lists what FOG sets in the boot script before the menu is drawn, so one entry can adapt itself to the machine reading it — ${hostname}, ${primac}, the host’s inventory, and more.

Custom Background

You can add a custom picture background.

Place the file in the following directory: /var/www/fog/service/ipxe

And use a resolution of 800x600.

Prelude for adding IPXE boot entries

If you have a lot of files for customboot entries i highly reccomend you put those files on a different webserver. This because CPU usage will be very high due to PHP FPM.

Adding a WindowsPE based image

First of all you need to need WIMBOOT. This is a tool that allows you to boot WindowsPE over IPXE and load the files into ram. You can download it here: https://github.com/ipxe/wimboot/releases/latest/download/wimboot

place those files on a webserver in a standalone folder.

After that you can add you unpacked iso the the webserver.

Now you need to create a customboot entry.

#tell IPXE to boot files loaded in ram
