Now in part 2 we will see how we can generate code and link it to GNU-EFI so it can run on the EFI environment, but first.

I asked ChatGPT... I'm kidding, I'm kidding. I'll copy more or less the wording on Wikipedia rather. UEFI (Unified Extensible Firmware Interface) is a specification for the firmware of computer systems that supports booting from a hardware-based EFI (Extensible Firmware Interface) environment, and it's used by both UEFI 1.0 & later versions as well with some older BIOSes like …

I have this idea of restoring the Mesa/Cedar compiler but discipline and skill are lacking. I have documented the progress I made from a archive that was released by the Computer History Museum while ago in https://github.com/xspager/Cedar_tools.

So I was the other day watching the a Data General Nova being restored (Usagi Electric playlist, Tech Tangents playlist) and wondered if I could get myself familiar with the software on that platform and see if that helps with recreating the kind of …

Let's write some code that uses the services provided by the (U)EFI (modern BIOS) environment and we gonna use Terra, as is says in their website, a counterpart to Lua. I'll assume that you know some C for Part 1.

"Terra is a low-level system programming language that is embedded in and meta-programmed by the Lua programming language". This means you can write some typed code that looks like Lua, embed some Lua code, and compile the whole thing to machine code.

To install Terra you should have a …
