Hi, we have an old mini mill, and have issues with the software, I saw once a technician doing something like starting up the machine and preparing it for receive new software, anyone knows the procedure for doing that?

we want to start testing the keyboard, but the controller is not responding properly, i tried this on another haas machine a year ago but i forgot it... it was a busy day, long story.
so if there is something wrong with the software i will call a techinican, but for now we are short of $$$ so i will test that first.

I remember something related to BIOS, i mean i could see the RAM available and stuffs like that, i tested the keyboard on that screen.

Regards
