Do you want to compile everything at once, or only kernel and drivers?

To compile kernel, download kernel sources in .7z format from download page, or download them from svn server.
Install FASM (http://www.flatassembler.net) properly. (this means you have to add fasm directory to your PATH variable on windows)
Run the build.bat (on windows) or makefile (on linux) you can find these files in /kernel/trunk/
Now, the compiled kernel and drivers will be in /kernel/trunk/bin/
The easiest thing to do now is inject these files into an existing kolibri.img file (use winimage on windows / dd on linux)
Now, you can create a booteable CD from the kolibri.img file (as descibed here: http://wiki.kolibrios.org/FAQ#How_to_wr ... to_a_CD.3F)

To compile fasm programs for kolibrios, compile the .asm file of the program with fasm to a file without file exstension (win32 fasm with gui will compile to *.bin, remove this from filename after compiling)
You can place your programs on the CD as regular files, or you can also inject them into kolibri.img like you did with kernel and drivers.

PS: try with a CD-RW first

Hi , thank you for your information, i interested in build all the operating system, to create a ISO image , i can create one like that downloading with the operating system booteable
