075f7ab4ca Now the Stage 1 of the bootloader loads Stage 2 in memory. 
I already wrote this but my computer crashed, so I won't write as much as before.
Now the bootloader is divided in stage1 and stage2, I added and edited some makefiles, stage 2 is written in Asm and C, the kernel isn't loaded into memory.

PS: after this commit I'll add another branch called "coding", the code in that branch won't work 100% because it's missing something, but I don't want to do a "mega commit" every time (those commits will still be in the main branch).
To everyone who wants to try XanvicOS or """using""" it, use the main branch, because the main branch's code is working.
I'll write this in the README.md right after this commit.

7a1c92972f Add bootloader's 2nd stage written in C and asm 
Now the bootloader is divided in stage1 and stage 2, the kernel isn't loaded so it's useless (for now).
The Stage 1 of the bootloader prints some strings and loads the second stage into memory. The second stage prints a hello world message.
After this commit I'll divide the main branch into stable and coding (stable is working code, like all the commits I did until this day, coding will be the branch where I push all the code I write, so there may be a lot of errors or the code doesn't compile. I you want to use or just try XanvicOS use the stable branch)

<h3>Why does this website exist?</h3>
I created this website because I wanted to.
<h3>What you'll be using this website for?</h3>
I'll use this website the things that I do.
<h3>What exacly is Xanvico and XanvicOS?</h3>
Xanvico is the name of our frind group.
<br>
XanvicOS is the operative system that we're working and I'll not use an existing kernel like the Linux or BSD ones because I hate my life.
<br>
The operative system will be a DOS like system that supports the x86_64 architecture that will execute 16,32 and 64 bit executable and the GNU/Linux (and if I can do it) and Windows ones.
<br>
In the future we'll think about developing source based package manager (like Gentoo's portage).
<br>
A GUI will be added in future (I hope it'll be a tiling window manager with some additions like an app menu, a bar like the waybar and others).

<h2>Benvenuto nell'archivio di Xanvico!</h2>
<h3>Perché questo sito esiste?</h3>
Ho creato questo sito perché avevo voglia di farlo.
<h3>A cosa serve questo sito?</h3>
Questo sito serve a pubblicare le peggio cavolate che faccio.
<h3>Cosa sono Xanvico e XanvicOS</h3>
Xanvico è il nome del gruppo di amici composto da me e altri 2 ragazzi.
<br>
XanvicOS è il sistema operativo su cui ̷s̷̷t̷̷i̷a̷̷m̷̷o̷ sto lavorando e non userò un kernel già esistente come quello linux o quello BSD perché odio la vita.
<br>
Il sistema operativo dovrebbe essere un sistema simile al DOS che supporta l'archittetura x86_64, ma che può avviarsi in una "DOS mode" (come Windows 9x, escludendo Windows ME) che in futuro sarà capace di eseguire nativamente gli eseguibili 16,32 e 64 bit e quelli di GNU/Linux e (se ci riesco) anche di Windows.
<br>
In futuro si penserà anche allo sviluppo di un package manager dove si può compilare tutti i pacchetti da sorgente (come Portage, package manager di Gentoo GNU/Linux, distro che sto attualmente usando) ma in futuro sarà anche possibile installare pacchetti già compilati dal sottoscritto.
<br>
Una GUI verrà aggiunta in futuro (spero che sia un tiling window manager con qualche aggiunta) e quando essa sarà stabile pubblicherò il codice sorgente su github in modo da farmi aiutare anche da altri.

<h3>Cos'è Xanvico/XanvicOS?</h3>
L'ho già spiegato nella pagina Home, non ho voglia di scrivere.
<h3>A che punto XanvicOS?</h3>
Si avvia in nella modalità 16 bit grazie ad un floppy formattato con FAT12 da cui il bootloader carica il kernel che fa apparire sullo schermo il messaggio di Hello World.
<h3>Come chiamerai il kernel di XanvicOS (ad esempio Linus Torvalds ha chiamato il suo Linux)?</h3>
Non ne ho la più pallida idea. Aiutami!
