Can you provide the full actionscript of what you are trying with the root server redacted from the prefetch if applicable?
Also, have you tried installing the firmware on the commandline by hand? You first need to be able to install it through the commandline without any interaction. Once you can do that, it should be straightforward to do the same through BigFix.

Thanks for tagging me.
I have automatically generated but mostly untested Dell BIOS Update fixlets here: https://github.com/jgstew/bigfix-content/tree/master/fixlet/BIOS/Dell
One major issue with testing these is that I can only really test with the models I have, which is generally like, 2 or 3 models. And in the case of Lenovo, I don’t have any on hand. On top of that, the process of rolling back a BIOS update in order to retest it over again is kind of annoying, and sometimes impossible.
