I spend a bit of time dissecting the #sunpci driver in #ghidra. And I can now boot the SunPCi from my own code! Using the #solaris driver still.
Some terrifying conclusions:
The windowed output in the SunPCi userspace application comes from repeatedly read()ing the /dev/sunpcidrv0 node. That just returns some raw video data and mode information.
Userspace contains a VGA emulator itself. Whenever it doesn't understand something it just switches to the external VGA.

Also note in the above screenshot that the "Award Modular BIOS" screen does not have the normal logo. But there's still SPACE for a logo.
The fact that the #sunpci did not show the Award logo bothered me from the start.
The reason for this is obvious now. The "Fake text mode" that the SunPCi application implements simply doesn't have support for the weird mixed text/graphics mode that the BIOS wants to use!

@hp I always wondered what it means specifically that the BIOS is modular.

Leggendo da più testate ho capito che era una pattuglia supplementare, che straordinariamente è stata aggiunta alla normale routine in zona, programmata proprio per quel giorno... 🤷

Ho provato a leggere ma non mi sembra ci siano patch. E poi, se è come scrivono perché sul cellulare sì e sul tablet no?

@Alberto @uriel "Operazione straordinaria" mi ricorda l'"Operazione speciale" di putin in Ucraina. Serve a non dire le cose come stanno.
E ovviamente era programmata.

I'm starting to believe that corporates' push to adopt #AI origins from desperation. They think that newer generations will never dive so deep to match older generations knowledge on base tdchnologies. Take IT: what we look at as a personal hobby, like "retro computing" is all about basics of computing. Find a 18yo that has the same knowledge. If you succeed, they will be *the exception*. If this is true, in 25 years, they will have extraordinary computer systems and infrastructure that nobody, except remaining AIs that learned something today, will be able to manage. And this scaries the shit out of the establishment.
So they try to fllee with the bag full of money today, because "FUCK YOU".
