It depends on where you have placed it! If you have installed kernel from distribution binary package, you have to download it first. If you have downloaded a source package, query your package manager program. If you compiled yourself, you should already know. > 2. if i have the device driver module's source code written for perticular > device than where should i store it, so that it will support to my device > whenever any user seeks it. If you have it in a form of patch, you apply it using patch -p1 <the-patch-file command in the top-level directory of kernel sources (unless the driver states otherwise) If you have sources that already have makefile to compile off-tree, you can place it anywhere. You just need to tell it where kernel headers reside (you may or may not need the whole tree - depends on the particular driver). If you have just a source without makefile, you may either place them in kernel (besides other drivers of the same type), modify the Makefiles and config and compile in kernel tree, or you can write makefile to make it compile separately. > 3.

Linux does not rely on swap space being present at all, so too little swap won't principialy hurt either. It's just your applications may not have enough space. In linux, each page is either in swap or in memory, so you have size of ram + swap available as virtual memory (part of that is used by kernel itself) > 4. what command should i type to know the version of my present OS. uname -r ------------------------------------------------------------------------------- Jan 'Bulb' Hudec <bulb@ucw.cz> -- Kernelnewbies: Help each other learn about the Linux kernel.
