Question about which tools to use, bugs, the best way to implement a function, etc should go here. Don't forget to see if your question is answered in the wiki first! When in doubt post here.

The kernel has a list of symbols built in (generated at build time), then it uses ebp to find the addresses of called functions and matches them to a symbol. The code is here: http://codebrowse.launchpad.net/~exclai ... wyj2zbb1-1

You can look at the kernel symbols stuff in ksyms.c and the generator in kernel.mak and genksyms.py

You can also get GRUB to load your symbol table in for you, and use that. I have some code for that if you like ;)

Here is my early attempt at a booting kernel (it can't be really called an OS)...

Haven't worked on my kernel for a while. But picked it back up tonight and started doing some work on it and fixed a couple bugs.

Anyway, Here are some screenshots of where its currently at.

Here's a screenshot of my OS in text mode:

My graphical manager doesn't work very well yet, but I'm fixing that in to-do 5 and 4 (I'm on 9 todos if you look at my profile) before I reach version 0.01.
My OS is Perception.

Here's a screenshot from the JBOOT which is the bootloader I have just finished writing.
Image
This screenshot is from JBOS MT which was scrapped after a while due to the lack of any design before I started coding.
Image
The final screenshot is of MYSTIC. I learnt from my mistakes with MT and thought about the design for it. The reason why it says "bootloader overcome" is because the previous bootloader I used set up paging and mapped the kernel to the higher half of memory which is not what I wanted so I reversed all of that. I therefore decided to write my own bootloader as well. JBOOT is the result of that.
