Hi... First of all, grab kernel source from kernel.org. Unpack, then do: make mrproper make menuconfig (make sure you have installed ncurses devel package here)...then do some configuration make bzImage make modules make modules_install then copy the kernel image, most likely in arch/x86/. Copy a file named bzImage to another directory. You can pick /boot for instance. Then configure GRUB or the boot loader of your choice. > Also i have one query. > > To boot my system do i really need to built the initrd file? shall i > use the existing initrd file which is there in my running PC? Quite likely yes. Unless you built everything as single kernel image, you will find some of kernel modules are needed during initial boot stage. This is why you need initrd. It acts as initial root filesystem containing modules needed to proceed into complete successful booting e.g loading ext3 kernel module to access real filesystem, loading LVM modules in case your root filesystem stays inside LVM etc etc Afterward, initrd has no use at all. It will be simply thrown away from RAM. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
