I once captured the Linux boot screen of a United Boeing 737 infotainment system. Apparently I still got that photo. OCRed text for lols:

I used to work adjacent to these exact systems...they're so bad.

Like, 10+ minute boot at times, or assigning multiple devices to the same IP, or the communication network just randomly dying... (and this was all in vitro testing)

It was still cool to see "the rack", aka an entire planes infotainment system setup on a rolling cart including however many seat backs each plane was supposed to have. They had multiple office buildings that were essentially full of these, because each airline and deployment was different enough that they didn't want to have to reconfigure when needing to test them.

Some of the time is because they have a single board computer, and only licensing the BIOS. You'll know if that's the case if after the boot, you see it purposely set the time to something arbitrary, but dating back to the 90's. To the flight entertainment, the date doesn't really matter. For the licensing however, it does.

Also elsewhere in the boot, you might notice they tend to be 80486 CPU emulation boards from Cyrix. They're not fast at all, but for what they do, they don't need to be.

Also, if you took video instead of a pic, there are a few interesting IP addresses might scroll by as the media program gets initialized.

Oh man, the NatSemi Geode (aka Cyrix MediaGX). What a system. I'm amazed anyone got a usable Linux system out of it at all.
