Where did this C kernel tutorial which I am seeing missing in several pages go to? --Frank 22:20, 1 July 2007 (CDT)

I think it refers to the "C kernel bare bones tutorial", which has been renamed a few times - Combuster 09:25, 2 July 2007 (CDT)
Yes, that is what the links should be. That was messy editing on my part. Sorry. -Jhawthorn 14:40, 2 July 2007 (CDT)

Intrepid Ibex repositories have the 2.03 which is ok for this. Can someone check the hardy repos please? <- Someone posted in the middle of the article Oros


According to http://forum.osdev.org/viewtopic.php?p=243327#p243327, you do not need to substract KERNEL_VIRTUAL_BASE from _loader . I deleted the _loader symbol, used only loader, and it works fine for me

Disputing

There are two obvious issues with this article. First, I needed to use ENTRY(_loader) and not ENTRY(loader), that is I needed to use the virtual entry address. Attempting to do otherwise resulted in the GRUB error described in the page. Second, it is not guaranteed that GRUB will put the multiboot structure in the lower 4 MiB.

After these, I can see no mention about mapping only the kernel (and not the whole lower 4 MiB), setting permissions to .text, .data, .rodata, .bss, etc, or setting the WP bit.
