Today is a good day :’)

After months of design considerations, documentation hell, various wall-banging, slow coding, and computer overheating due to Bochs, I’m finally one step closer towards being done with my bootstrap 32-bit kernel and starting work on the 64-bit C++ one. Because finally, I’m done collecting information needed by the main kernel (command line, bootloader name, startup drive, and a map of memory describing which places are free to use, which places are used, and how each place is used). I feel so proud, right now…

Kernel information displayed using debug routines, aka "Hell, it's about time !"
See the power of OS development !

I know, it sucks compared to what’s around, even in the OS hobbyist world. It’s just some debug info displayed using some debug routines (that I’m proud of too) in a pretty fashion. But well… I guess that’s what parents feel facing their child who just stood…

    Erm why shouldn’t it be impressive? Let’s just say that what you coded is rather more complicated that MOV AX,4C00;INT 21H kind of code.

    Keep up the good work! :)

    Because it took me more than a month of work to get and store in an unified way information that GRUB collects for me (command-line, bootloader name, startup drive) or should be collecting for me (full memory map).

    Though to do that, I had to write and use hundreds of lines of debug code, and learn a lot about things like linker scripts, ELF file format and symbols which could certainly be useful later, especially if I have to modify this code. And I had some other work to do at the same time. So maybe you’re right and it’s not too bad for a first attempt at OS-deving ;)
