OSDev.org

I have been searching the web for days now for a application similiar to
makeboot (just that i need it for linux), which can be used to put a simple bootsector and kernel together in a raw floppy-image file which can boot with bochs or be written onto a real floppy afterwards.
I tried recompiling makeboot under linux, but the imagefile that was created by my recompiled makeboot was messed up and did not work properly.
I tried an image created under windows before and it was laded correctly.
So the problem i this little tool...

After setting up bochs inside wine (it would not run directly with linux) this would be the last step i need, before i can go on with OSDev and lowlevel experiments only under linux and without rebooting all the time..

Please tell me a command or application to use!
Thanks in advance!

How about DD ? Don't know what the beginning was... seek ? ::)

Code: Select all

dd if=input file of=output file skip=totalsectors to skip

Don't know what the beginning was... seek ? ::)

I have already tried it in several ways, but bochs did not accept it..:
i tried:
cp bootsector.bin bochs/1.44
dd if=kernel.bin of=bochs/1.44 skip=1
With skip =1 because the bootsector is 1 sector....
i also tried it without the skip.
And i did not find anything about using 2 input files and one output file automatically.

cp bootsector.bin bochs/1.44
dd if=kernel.bin of=bochs/1.44 skip=1

To create an image in linux:
After you compile both the bootsector and the kernel, type:
cat bootsector.bin kernel.bin >os_image.img

Then copy the image file to the bochs directory, add the name to the bochsrc file and boot it.

Hope this helps.

check the OS faq on this site, it has image instructions.
