Installing CircuitPythonįirst, I had to install CircuitPython on my Pi Pico. I was mostly interested in seeing what the Pi Pico had to offer, plus it was cheaper and more compact than an Arduino Uno. Some arduinos can emulate an HID keyboard, but I chose to use a Raspberry Pi Pico instead. To fix this, I’m going to emulate a keyboard pressing the ‘F1’ key shortly after the machine powers on. This makes it really annoying to turn the machine on! The worst part is that you need to pull out a keyboard and press the F1 key to continue.
I’ve looked through all the BIOS settings, and there’s no way of disabling this warning dialog. Everytime the machine boots, a warning is displayed saying that the graphics card is running in PCI x1 mode. My arcade machine’s graphics card doesn’t want to play nicely with its motherboard.
