Could anyone give me a step by step guide on how to correctly compile the kernel. When i compile the kernel using the command "fasm kernel.asm kernel.mnt" it seems to compile just fine. I end up with a kernel.mnt file which is 141Kb in size. But when i copy this newly compiled kernel into the existing kolibri.img (0.7.7.0 - Kernel compiled from downloaded 0.7.7.0 source.) it will not boot, I also noticed that the existing kernel.mnt was only 70Kb in size.

I'm learning to program in assembly and would love to use KolibriOS as my learning platform.

You doing everything right. The kernel in 0.7.7.0 is compressed using kerpack (you can find this programm in kolibri.img).

I now tried to use the kpack.exe to pack the kernel.mnt file i compiler, it's now almost the same size, 67.2Kb. I then copied this file into the kolibri.img file, overwriting the existing kernel.mnt. Then used ImgBurn and made a bootable .iso from the modified kolibri.img file.

But when i tried booting from that .iso in VMWare it stoped at "Starting System...............".

Any clue what might be wrong? The kernel.asm i compiled is the original kernel.asm from the 0.7.7.0 source download, I've not modified it in any way. Want to be able to compile and test before i start trying to modify the code.

I figured it out!

When i copied the file onto the Ram Drive in KolibriOS and then saved a new image and then made an iso from that image it worked. I used MagicISO earlier to copy the kernel into the kolibri.img file.

But thanks anyway for your comment/help...

kpack.exe - for applications
kerpack - (Kolibri binary executable) - for kernel.mnt

Hi,

Sorry to pop-up in the middle of your discussion but I have a related question...

First let me tell you I just love what you are doing: an assembly OS that releases all the capabilities of the hardware for the applications, and applications that preserve performance for the end-user has been my dream for years.

Consequently I like to get a look at your code: using Windows and Linux, I can modify and compile the kernel, write in kolibri.img, boot on USB, but I cannot easily compress yet. Actually I would like to recompile kerpack as an .exe to be able to compile and compress at once (I am using Windows for compilation).

**And my question comes here**: kerpack.asm is missing in kolibri_0.7.7.0_src/programs/system/kerpack. It should be there since it is referred by keypack.bat. I cannot find it also in the other packages of Kolibri 0.7.7.0.

Is there a way to get kerpack.asm or kerpack.exe somewhere?

Thanks in advance.

Fixed in the latest night build (http://diamond.kolibrios.org/nightbuild/).

Thanks for your fast reply! I'll go on.
