10 This is the supplemental source code for the first part of the introduction to
|
|
nuclear@4
|
11 kernel development articles. It deals with booting up from a multiboot-compliant
|
|
nuclear@4
|
12 boot loader and using the VGA for text output.

14 Compiling & Running
|
|
nuclear@4
|
15 -------------------
|
|
nuclear@4
|
16 To compile kernel image (kernel.elf) just type make (or gmake, if your default
|
|
nuclear@4
|
17 make tool is not GNU make). A script called "run" is supplied that will use qemu
|
|
nuclear@4
|
18 to run the kernel in a virtual machine.
|
|
nuclear@4
|
19
|
|
nuclear@4
|
20 If you wish to boot up the kernel on your computer you need a multiboot
|
|
nuclear@4
|
21 compliant boot loader like GRUB. Since you probably already have GRUB installed
|
|
nuclear@4
|
22 if you're running a GNU/Linux distribution, just add an entry to the GRUB config
|
|
nuclear@4
|
23 file (commonly /boot/grub/menu.lst) similar to this one and reboot:

|
25 title My kernel
|
|
nuclear@4
|
26 root (hdX,Y) # where X is the disk number and Y the partition (first being 0)
|
|
nuclear@4
|
27 kernel /path/to/kernel_code/kernel.elf # change this to the actual path
|
|
nuclear@4
|
28
|
|
nuclear@4
|
29 In case you are using GRUB 2 instead of the original GRUB, you'll have to
|
|
nuclear@4
|
30 consult the documentation on how to modify the above into the GRUB 2 syntax.

33 ----------
|
|
nuclear@4
|
34 All programs contain bugs, and this sample code will undoubtedly have its share.
|
|
nuclear@4
|
35 Running buggy kernel code on the real machine is very dangerous and may result
|
|
nuclear@4
|
36 in data loss or even damage to your computer in extreme cases. The author

nuclear@4

38 computer at your own risk.
