PIRONMAN 5 cd ironman not found

Hi All

I had the pironman 5 working and I tried to install the nvme.
Long story, so I installed a fresh os of Bookwork on the sd card.
The system boots ups but no oled and the fans and light are constantly on.
Following some of the post I tried to cd pironman response was not found.
I probably erased it.

It is recommended that you follow our online tutorial steps to download and install the pironman5 software:

Thanks
I followed the guide and everything is good now
