In PCs, when you turn on the machine, the system reads BIOS to locate the MBR which is the first 512 byte of hard disk. Then, the MBR says the location of GRUB and the
GRUB program starts to load kernel. Finally, the kernel loads modules and init scripts to boot system up. IN ARM system, because we do not have any BIOS or Hard disk, the
process is different and it dose not have any GRUB. Instead, it has a Ramdisk or an image from file system that kernel loads that and boots from that. SoNow, we are going to make a package or RPM in case that wehave several kernels installed in ARM, and it should figure out to select the current kernel that it wants to load because it does not have any GRUB like PCs. So, this is the first approach for this project.
