Why do you lil' shits keep making LAYERS and LAYERS of unnecessary abstraction and then call it goddamn progress???
Dude what the fuck is this UEFI shit?!
Why the hell do I NEED to import a frigging library and read tons of boring and overly complicated documentation just so I can paint a pixel on the screen now uh??
Alright alright yeah so the BIOS is a little basic but daaaamit son if you want something a bit more complicated you make it yourself or install an OS that provides it! Like we've been doing it for years!!!
Dude, you don't get to know what a file system is until I tell you!
The PC be like:
"You wanna dereference the 0x0 pointer? There you go: it's 0xE9DF41, anything else?
You wanna write to the screen? Ok I have a perfectly convinient interrupt setup for that.
Wanna paint a pixel yellow? Ok, just call this other interruption. Theere we go.
And it only took four bytes and a nanosecond to do it."

That shit works, and if you want something more complex, but not too much, that still runs efficiently install DOS.
Don't mess around with the hardware pleeease.
We can still understand what's going on down there. Once UEFI steps in, it'll be like sealing a door forever. Long live BIOS damn it all!
